Awesome man, thanks very much for the advice. DIdnt get a chance to test it tonight but I will as soon as I get home from work tomorrow. Respect!It's definitely just timing, d3 recovers much faster than uppercuts so if you time it just right it looks like the d3->d2 is seamless. I'd say it's just a timing/patience thing, you actually have more than enough time to do all 3 off a 11 bf1 cancel, but you can't mash (I used to mash d2s during bf1 until I realized that particular optimal doesn't allow for it).
If you're patient and wait for the uppercuts to complete you should be good.
