Oh God is that Oppose AAAAAAAAAA (Ram RRC starter combo)
See https://youtu.be/wO2Ue_zqQoI for a similar idea on Pot. If you end with Calvados instead of 214HS you do 246 damage. If you're further away from Zato you'll have to drift forward instead of up on the RRC, the combo is still possible but it's harder and does less damage (upwards RRC sends the opponent higher and is a better starter for damage scaling purposes).
I think Pot and Zato are the only matchups where you really have to think about comboing off RRC. If you RC a move after hitting Anji's guardpoint the screen slowdown will give you a PRC which doesn't count as a hit. Leo's guardpoint stance blocks RRCs so that's no good either.
