Sorry I'm relatively new to a lot of sensitivity converters, I've only just today realized there's a science to it. Usually I just did continual tweaking through in-game settings until I found a somewhat tight fit (which took anywhere from 20-40 minutes of trial and error). I did however notice that there was the thread linked and I did submit it. Every drop counts.
Thanks for the tip of advice though. I'll go with the 'Brandon Method' and see how it feels!
Edit: I am a bit confused about Vertical and Horizontal sensitivity. I inputted in as much as the information I get, but should they be equal values? Or should I use what they are defaulted to? Nothing in the calculator covered these values.
