The idea is to crush the crush washer and then index it to the direction you want. Since that comp doesn't really have an "up" direction, I would probably recommend just going until the crush washer is close to flattened out. Don't overdo it, its not necessary. The idea of the crush washer is that it will create torque by exerting force against the comp once it starts to crush. Think about how most people use them, right? We go hand tight, then use the wrench to start flattening the washer, then turn to align "up" and then stop. The final torque is what it is. I have one that I had to go almost an extra 300 degrees to align, and another that I only had to go about 180 degrees, and both never move. So don't overthink it for this. As long as the washer is starting to crush, its not coming off. If you're really worried and want some peace of mind, scribe a line on the bottom out of sight with something you can easily clean off later like wax pencil or even a sharpie, and after shooting check it. It'll most likely be exactly where it should be. Then you can clean it off with some acetone or oil.
