Well, I'm not a pro player at all, but I have a couple of years of experience, so I can say some of
my opinions:
What you MUST:
- You must set the mouse sensitivity as an enough high number to be able to look around.

My test is, that you must be able to do one continuous move of the mouse which makes you turn in the game for 180 degrees (to look behind yourself). Actually, you don't need to turn more - I will return to it later.
- But you must set the mouse sensitivity as an enough low number to be able to hit with the sniper rifle a non-moving target in an arbitrary distance. Without zooming and you should do it with ease.
Now these are in my opinion two basic boundaries of successfull sniping (or generally aiming).
Now my opinion is, that - You don't need higher mouse sensitivity, than the value, which allows you to look behind comfortably (as I noticed before). If you had the higher value, you would lost the precision of course. But what would you gain? The possibility to do 720 degrees with one move? To be able to turn around like a carousel?

Thats useless imo.
Thats one point for "The lowest sensitivity".
Next one - You will agree, that the lower sensitivity is, the more comfortably you can hit the long range targets. Thats the second point for "The lowest sensitivity".
I personally have also almost the lowest boundary of mouse sensitivity and I heard, that many pro players have it the same.
Well, i need to notice, that I spent quite a lot of time to set it to the best value for me. But if you do it and you take some time go get used to it, you will feel, like the cursor in the game is just the continuing of your hand.
What I could recommend for testing - first, go, walk alone in the map and just look around, if you're able to see everywhere comfortably. Next one, take a pack of Novice bots, sniper arena and some large enough map - Deck-16][ for example and try, if you are really able to hit the non-moving targets comfortably.
These are some of my opinions.. Hope that help.
