Yeah, that's right.
I just loaded up BB to test a few things. I couldn't get 236D> 66 to work.. I'm not really sure how it would work? You don't mean a dash after you hit with the 236D right? This is a dash before the 236D starts up. You always das after the 236 D hits, but the additional dash before helps for getting you close enough to consistently get the 5c.
I also tested 99. On my pad this resulted in a lot of IADs, the input window showed a lot of non diagonals when I was doing it. Doing it on the analog, raw 99s, yeah that was just double jumps.
