The 3330 is probably the most complex lock of these which do not have manipulation protection measurements. The eggness of the wheel depends on code, position, direction and perhaps other things. Manipulation is the optimize the lever position, i.e. to find the absolute lowest position while accepting local minima. With 18/51/58, I would have made these 6 possible combinations. When the lock did not open I would have use the lowest position of these. If you change direction from AWR to L-R-L you must not forget to correct the number for direction change. The offset is somewhere between +0.5/+1.0/+1.5 and +1/+2/+3. So changing from 18 on W1 from R to L means you go to 18 and then between 1.5 and 3 further. You should test this on your lock. Turn all wheels R (or L) to exactly e.g. 50. Then switch direction, dial to 50 and feel where W3 picks up, then make another round and feel where W2 picks up, and then W1. Starting from the above determined best position I would start to optimize each wheel on its own.
