Yeah you almost always want to keep the pressure up.. I mean, even if you walk right in to a reversal, you just taught him its a good idea to reversal on his wakeup.. So next time you knock his ass down, go in like you did, but block instead, so you can CC his reversal and poop on his life bar. I mean, most CC reversal punishes are around 275-300 damage on the low end, with a few exceptions being lower and MANY being *way* higher depending on resources and such.. Since a reversal does 100-140 damage on average, he has to land two-three reversals to equal the damage of your one punish and thats low end.. If you have a higher punish on deck, 350-400+ than he has to land three-four to equal the damage. Thats VERY much in your favor.
Honestly, this game is *almost* exclusively about intelligent pressure, so if you arent applying it (like me) you arent playing the game right (like me). Aside from very basic stuff like AAs and the most basic of BnBs, your pressure post knockdown is about the most important thing there is to learn in this game.
