ADoFaI’s parallelogram loops, which indicate a tightly swung “1-23-45” rhythm, are my weakness. I have also found myself losing traction on long square/hexagon/octagon loops. However, I have been practicing the former matter, and . . . I wouldn't say that I've improved substantially, but I have gained enough skill to sometimes get past the very fast parallelogram at the start of Party of Spirits.
Expect footage of my practicing to be broadcast on RW-570 soon.
