I tend to start with a dash, rapidly click over the duration of the 3 next hits, and then swipe twice (just to be sure I get the Medium hit). When I started, I was spamming that thing like crazy, 9+ times. I've tried tapping exactly 4 times, but feel like I sometimes miss hits. Probably tap around 6-7 times now during the combo, but curious what other people do... maybe I'm just weird o_O
