I mean it's much more easier to do the spin if you do it the same way every time, his Reimu A and Reimu B WR's were 9 days apart which is already fishy enough, but they both use different timings for the spins too. ReimuA is timing #2, #2, #2 and ReimuB is timing #1, #1 and #2. Just to put it out there his MarisaA timings were #1, #2 and #1. There is no graze difference or any other gain from doing them differently.
