Quoted from fisheye

i think he just meant that:
if you set this new command to, let’s say 10, and mp_windifference to 2, the game won’t end if scores are for example 2:0, 5:1, 9:7, only when one of the teams has 10 points. so the valid ending will now be 10:8, 11:9, etc.

this is directly from console:
“mp_windifference_min” = “0” min. 0.000000
game notify replicated
– Minimum score needed for mp_windifference to be applied
