Warmup on higher sens

I heard about this few months ago and it actually helped me with controlling my sens.
Warmup with higher sens,
Play with lower.

Do you guys know any pros using this warmup?
I think trent did it but i am not sure

Im a pro and i can confirm I do it ( I peaked plat)

demon1 uses higher sens on aimlabs i think

this is bad unless its outside of game. Like Aimlabs/Kovakks , when warming up in a dm it could throw your timing off on when swinging angles and holding them. wouldnt do this in valorant
