2 finger scroll erratic and slow on 2012 MBA

[HarryWarden]

Bought a MBA on Black Friday last year. The trackpad works fine for clicking and the pinch-to-zoom gesture in Safari. However, 2-finger scrolling in Safari and Firefox isn't nearly as precise as the same thing was on my 2009 MBP. I've tried adjusting the related setting in the Accessibility menu but it makes little to no difference.

1. Clean.
2. Reset SMC.
3. Reload Clean OS. (BU data 1st obviously)

I get this too on my 2012 MBA.
