Question regarding the "T" part of KAST rating
A very common statistic used in rating player performance is KAST rating (Kill Assist Survival Traded).
I've been working on an analysis tool for CS:GO, but I've noticed the KAST rating calculations I've come up with vary a bit from sites such as HLTV. So here's the question. Is there an official definition of a "Trade-kill"?
In my current implementation, if the follow-up kill happens within about 3½ seconds of the initial kill, it's considered a trade, but this is just loosely based on my own experience in the game. I'm finding this duration to be long enough for a teammate to move out and land the shots, and short enough to not include kills not related to the initial engagement.
I realize it's a long shot asking here, but if anyone happen to know a proper definition of a trade-kill, I'm very interested

A trade kill can take longer than 3 and a half sec, though it shouldnt optimally speaking... But a mate can still trade the kill after a around 10s even

While I agree it's more complicated than just a set time period, I feel 10 seconds is way too much.
The improvement to KAST rating happens because the sacrifice needs to directly impact the subsequent kill by the victims teammate.
After 10 seconds the opponent could've thrown a Flashbang, reloaded and repositioned, at which point, the initial engagement no longer has any meaningful effect on the subsequent kill.

No i agree completely.. I am just saying in my optics 10 seconds can go by before the trade occurs at rare times... And that i think its just a really fkin complicated thing to do stats on if ur gonna do it perfectly.
If you have a more detailed definition of a tradekill I'm all ears, but simply raising the limit to 10 seconds will not, in my opinion, give a more accurate KAST rating.
