Whoa! I considered mine unusably bad when I was getting 15-20 steps to clear it. When I got mine down to 4-5 then I could guide in both directions without it affecting the guiding too badly. Of course it's commonly recommended that you only guide in one direction, but I was never completely happy with that since the drift would change over time and there was always the odd anomaly that needed correcting.
I always found guiding in RA was much better closer to the pole than the equator. I read somewhere it's due to periodic error having less of an impact closer to the poles, though I don't understand the mechanics of that. I'd get around 0.5 close to the pole, but more like 0.6-0.8 close to the equator.
