I've tried hitting the right frame for this Registeel 4 times now, and the results are very inconsistent for some reason. At this point I have no idea whether I can actually hit that frame, simply because it takes so long for every try. However, I am completely 100% positive that I can get a Careful 30 / 31 / 30 / X / 29 / X spread if that's still ok.
I can still do the move tutor moves and everything, of course, but it's your decision.
