Is there a good method for timing when to dash after OHK? I have been practicing this nonstop before every session, and I still cannot seem to get it consistently. I have done this in May's mission mode and have watched the inputs, as well as watched a bunch of videos with it but still cannot land it consistently. It feels that this is really unforgiving on timing. I have a video of many attempts to do it with failure if you'd like to see.
