Let me do something nasty and compare MB to SF and to me it feels like that the DP input in MBAACC is a lot more inconsistent than in SF. I'm guessing it's lack of practice (yes, yes >practicing DP hurrdurr what is this 2007? new to the series).
But yes. Does the DP have any quirks about it that I should know that could be throwing off my constancy with pulling it off?
