Compo regens at like 2% of a plate every second. That's not quick at all. If a gren can put an RPG on a particular side every 15s (RPG cycle time is only 3s), then compo regens 16HP on that plate. RPGs do 130HP of damage per shot, so they completely blow past any regen. I'm tired of people continuously claiming that vehicle armors can regen faster than a gren can damage them. It's not even close. There is absolutely no discussion on this topic. There is no rebuttal. It is simply a patently false claim.
