You can set the error down from 50 pixels but if you do this you may need to increase the attempts depending on what your mount is capable of.
Yes, we could do a nudge to the target but really that isn't guaranteed to get you there any faster. Probably slower to be honest. Your mount should know your backlash vectors and be able to accurately slew while accounting for backlash. We wouldn't have any idea about backlash so if we were to nudge we could be jumping around quite a bit.
Really your mount should have the best chance of getting you where you want to be pointed!
