What finally clicked is the key is to getting a lock to pick is the interplay between the tension applied to the tension tool and the pick. If you vary them, and sort of push back and forth between the two (thus adapting the tensions) to sort of tweak the tensions, you can learn to get it right - the right amount of rotational tension and the right amount of lifting tension on each pin. It seems to vary with each lock as well - my master 3 is much more difficult (probably since it's keyed with shallow cuts) and requires more tension than the #1.
Just thought I'd pass on what made the difference here in getting reproducible results. Made learning security pins almost easy as well (after reading the info on this board about how to approach them of course). Can get the #3 at will now, and picked the 140 at last
