Not sure how I would calculate success since the only way I would fail is if I give up or if a lockpick breaks. I locked the two masterlocks and tried to rake them open again. Manage to open one in a minute or two but had trouble on the second one so I gave up. Will probably give another try tonight. Not sure what I'm doing wrong.
That sounds like a 50% to me, you got one open quick then didn't on the next. I see the frustration.
But that's pretty rad man. Just keep at it and you'll get it.
Myself, I never thought I'd get better at guitar, but I usually tinker with it after work almost every single day to do something different with my hands so I don't just kill my fingers.
