Making desktop sens 1:1 with in-game sens

[Arramis]

I was wondering if anyone would know how to find out what pointer speed/dpi would make moving a cursor around on windows simulate my in-game overwatch sens? I find that when ever I try to snap to  a window or a tab, I'm often consistenly a few centimetres short. Now obviously this isnt an issue, but i was thinking if could make this feel 1:1 it could potentially reduce warm-up time/improve muscle memory.
I play on 2000dpi/1.7

I dont really know how i would even work this out aside from just abritrarily making the cursor distance from left to right the same as my cm/360 or 180 in game.

Any suggestions?

0% monitor distance match is the best you can do.
