Bloubul, Having seen your spreadsheet, I conclude that dates are irrelevant because its a daily draw and therefore the skip between matches (draw against draw) is numerically the same (in days) as it is in skips. Why you kept saying "now" escapes me, as now is irrelevant from what I've seen.
There may be a more elegant way of doing this in a single column, but I'm using two columns.
To replicate your example using formulas, (and correct your mistakes)
try this:- In cells Y3 and Z3 enter zero .
In cell Z4 enter =IF(COUNTIF(S3:X3,">0"),0,Z3+1)
copy this down to the bottom of the range, to cell Z51.
In cell Y4 enter =IF(COUNTIF(S4:X4,">0")=0,"",Z4+1)
copy this formula down to the bottom of the range to cell Y51
The column Z is just a counter column which you can format in pale grey or hide the column if you don't wish to see it.
This replicates your example, I hope its doing what you asked.
