I don't think count really matters on the flow, a lot of great MC ryhme off count, RZA and Ghost pop in mind. You do need rthym, but your flow was nice to me on that song, plus a good mixer can fix the small little overlaps. Now on a keyboard it has to be right if your looping tracks, but that something that done mostly by ear and quantizing.
James Brown said he was told a million time his songs and beats were musically mathematically wrong, but he said if it sounds good you can't argue with Gods ears.
