After playing around with the findings of circ and red star its way more profitable to end in 8 or 11 after heat. 9 is just too random, I don't think I've got 9 to be a hard knockdown actually. So unless ur going to kill, the setup in the true corner is well worth the roughly 20-30 damage you lost.
So let's work on max damage heat ending in 8 or 11 combos. Sigh ,pot you're killing me bro.
