Can't set mouse sensitivity to certain values

Needs explanation and screenshots. You can't scroll it to 103%, that's it?

EDIT: Ok, I tested it, and I suggest you to edit it to say "Scroll skips 103%". It just goes from 102 to 104

Does the bar end at 103%?

No, 100 % is in the middle and the settings to the right are 101%, 102%, 104%, 105% ....
BTW: 117% is missing too.

In the options.txt 100% is stated by 0.5 and 200% (HYPERSPEED) is 1 - so 0.515 would be 103%? (Not too got a maths)

110% misses too, along with 113% and I can say it's the same with others followin a strange algorithm

Try sliding from yawn to HYPERSPEED!!! really slowly, about 50% of the numbers get skipped. I can confirm this.

I propose to close this ticket, apparently this is a cosmetic bug caused by rounding issues or whatever, but the gameplay is clearly in no way affected by not being able to set the sensitivity to 103% - 102% or 104% will work fine for everyone.

Closing this issue now.
Just take the slider's position as actual setting and the numerical value simply as the nearest representation of the slider's position.
