Sensitivity ratio...?

Hello!

I recently started really enjoying Sniper and with that came the question: What zoom sensitivity ratio should I use? I started (understandably) with 1 went up to 1.05 and back to 1. But I heard somewhere that 8.3333333 is the best ratio, so I tried it and it didn't feel right.

So my question is, should I continue to use 1 or learn with 8.333333?

Thanks :D
