I'm trying to count each rows of empty cells between two non-empy cells and adding the upper non empty-cell count (or the lower non-empty cells count) to the result when the empty cells/rows numbers are variable and irregular in this manner:
A1 Empty
A2 Non-empty
A3 Empty
A4 Empty
A5 Empty
A6 Empty
A7 Non-empty
(with A2 to A5 being irregular — could be any number of intermediary empty rows/cells — i.e. 10, 2, 30, 5, etc., and variable — could be located in any location within Column A)
The result should return as follow:
=IFS(
AND(A2="",A3=""),"",
AND(A2="",A3<>""),"",
AND(A2<>"",A3<>""),ROWS(A2),
AND(A2<>"",A3=""),ROWS(A2:UP TO NEXT NON-EMPTY ROW BENEATH (NOT COMPRISED (or minus the next non-empty row(-1)))
How do we program Google Sheets to count rows "UP TO NEXT NON-EMPTY ROW BENEATH (NOT COMPRISED (or minus the next ono empty row(-1)) when the emppty intermediary rows' count is variable/unknown for each occurence and irregular/can be any number of intremediary rows?
I have this data as example:
So far, I've come up with this partial solution:
=IFS(AND(A2="",A3=""),"", AND(A2="",A3<>""),"", AND(A2<>"",A3<>""),ROWS(A2), AND(A2<>"",A3=""),ROWS(A2:UP TO NEXT NON-EMPTY ROW BENEATH (NOT COMPRISED (or minus the next non-empty row(-1)))))
The expected result should return as follows:

Well I think you can do it a bit more elegantly using a reverse lookup. The idea is to sort the data on descending order of row number, then use a match with -1 as the last parameter, which is equivalent to searching from the end of the data for the next non-blank.
=ArrayFormula(iferror(if(A2:A="","",rows(A2:A)+2-match(row(A2:A)+1,
query(SORT({IF(A2:A<>"",row(A2:A),""),row(A2:A)},2,false),"select Col1"),-1)-row(A2:A)),1))
If you wanted to keep it simple and just use a pull-down formula, an ordinary match is enough:
=ArrayFormula(iferror(if(A2="","",match(true,A3:A<>"",0)),1))
(it still has to be entered as an array formula because A3:A<>"" is an array of True and False)
I found a solution with a Monster formula but with simple iterative logics, and up to 50 intermediary blanks (for more only need to make the formula larger).
What I was lookind for was simply to print the cells/rows count of intermediary empty cells between 2 non-empty cells + adding to the count either the 1st non-empty cell or the last non-empty cell.
So for example if cell A1 and cell A9 have 8 empty cells between them, then return 8+1 (or 10-1).
The logics used is simple:
probe how many possible empty cells there can be between each 2 non-empty cells counting the 1st non-empty as well within column A (in the formula below the possibility is up to 50 empty cells), and for each case return the intermediary rows -1 (the last row).
The formula:
=IFS(AND(A1="",A2=""),"",AND(A1="",A2<>""),"",AND(A1<>"",A2<>""),ROWS(A1),AND(A1<>"",A2="",A3<>""),ROWS(A1:A3)-1,AND(A1<>"",A2="",A3="",A4<>""),ROWS(A1:A4)-1,AND(A1<>"",A2="",A3="",A4="",A5<>""),ROWS(A1:A5)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6<>""),ROWS(A1:A6)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7<>""),ROWS(A1:A7)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8<>""),ROWS(A1:A8)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9<>""),ROWS(A1:A9)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10<>""),ROWS(A1:A10)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11<>""),ROWS(A1:A11)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12<>""),ROWS(A1:A12)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13<>""),ROWS(A1:A13)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14<>""),ROWS(A1:A14)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15<>""),ROWS(A1:A15)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16<>""),ROWS(A1:A16)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17<>""),ROWS(A1:A17)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18<>""),ROWS(A1:A18)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19<>""),ROWS(A1:A19)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20<>""),ROWS(A1:A20)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21<>""),ROWS(A1:A21)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22<>""),ROWS(A1:A22)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23<>""),ROWS(A1:A23)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24<>""),ROWS(A1:A24)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25<>""),ROWS(A1:A25)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26<>""),ROWS(A1:A26)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27<>""),ROWS(A1:A27)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28<>""),ROWS(A1:A28)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29<>""),ROWS(A1:A29)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30<>""),ROWS(A1:A30)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31<>""),ROWS(A1:A31)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31="",A32<>""),ROWS(A1:A32)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31="",A32="",A33<>""),ROWS(A1:A33)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31="",A32="",A33="",A34<>""),ROWS(A1:A34)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31="",A32="",A33="",A34="",A35<>""),ROWS(A1:A35)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",

Can it be done in a simpler way but still with a single formula?
Thanks a lot for your next input!
In the mean time I did some simplification of my previous Monster formula and learned the ArrayFormula application in the process.
1st I tried to shorten the big blank cells intervals into ranges formulations to see if it still worked.
For example I changed:
AND(A1<>"",A2="",A3="",A4<>""),ROWS(A1:A4)-1,
into
AND(A1<>"",A2:A3="",A4<>""),ROWS(A1:A4)-1,
And it shortened my formula from this:
to this:
But then when pasting the new formula I got a #VALUE! error 'an array value could not be found'.
After further tests, I used the ArrayFormula and it worked by adapting the simple 'ranges' previously used to Arrays:
from this
AND(A1<>"",A2:A3="",A4<>""),ROWS(A1:A4)-1,
into this
AND(A1<>"",ArrayFormula(A2:A3=""),A4<>""),ROWS(A1:A4)-1,
With this final result:
