Some of your akimbo accuracy is actually even better than mine! I think your aim is great, but sometimes it can be difficult to control the recoil on the AR, it's very different from the weapons in Sauerbraten that are more easy (imo) to control.
I've also noticed that when aiming with AR, you're very good at consistently keeping your crosshair on an enemy, however it appears a little bit "shaky", and I was wondering two things:
1) What sensitivity are you using? (cm/360?) 2) Do you play with mouse acceleration on?
Personally I think you might benefit from a lower sensitivity, and if you have mouse accel on then for the love of god disable it x) If you want it disabled from your entire computer, there's a patch available to download HERE!
