Eyeball it, then use your gage to make sure throws are consistent (ailerons same, elevator same, etc). Numbers in the manual are a reference, you will most likely end up changing the throws to your liking. Common start points are 10deg ail/ele and 45 (I think) for rudder. I used to try the conversions and use numbers, but after making changes I got tired of keeping track and doing math.

The throws on my Wind are so far below the recommendations in the manual, maybe 7 degrees now. If you have dual/triple rates, you can do something like 5deg, 10deg, and 15deg. Takeoff at 10 and switch if needed.
