Sorry for not pinging before on this, but I'm not noticing a significant change in trackpad behaviour (certainly does not seem to have deteriorated so could be a mild improvement). I need to sit down and do side by side comparisons while not being distracted by other tasks (just got back to Edinburgh tonight so I have a 0.82 XO-1 and F11-on-XO-1 handy again). A good test I used to try when the trackpad was being hacked on before was using Paint (same version) to draw spirals, you:
1) try to keep it reasonably tight
2) stop if you collide or get sloppy
3) count the number of cycles
4) try again N times
5) use the average cycles as a measure
Will give this a shot in the next few days.
