the PC heavy donkey kick combo does 70.8% damage (sorry for bad english)

They saucy tho. They saucy.

You use combos like these to close out a round when the opponent is around 50% health. If you never learn these, you'll never clutch and win back rounds on opponent mistake. But he's making them more complicated than they need to be. Ryu has a very simple combo route in general with around 5500-6000 damage depending on the situation. As long as you know how to microwalk, you'll consistently gett 5500+ damage anyway off an any standing conversion. And anti air ones don't need to be that complicated. You can do much simpler stuff yet do about 100 less damage and still close out a round.
