Yeah I think some of the issue here is games likely just cheat math to get an answer then remove said cheat once the math works how they want again.
So something like K:D if D=0 then D is 1. Beyond that they can release the rule and let it work normally.
Otherwise to get the stat before someone has died it would have to briefly run on a kill per life. I think…
