I think my OHB APM was at its peak around 5-10 years ago. I'll be the first to admit I prefer allgears so I can lean on the production quite a bit. I think most of my OHB stuff from back then was excessively chaotic. Obviously, it would be nice to work faster, but I think it can come at the cost of not being mindful about what you're doing. The only thing I can suggest is try some OHBs where you think as little as possible and just do to see what happens.
