No, that's pretty normal - reinforcement via generally "doing stuff" is pretty powerful (even in cases like this where the CG activity doesn't score directly), whereas undermining via generally "doing stuff" is very weak (and a lot of deliberate undermining actions are illegal so make doing the CG itself more difficult), so in almost all cases CG systems get strongly reinforced just through having a lot of players present in the system even though roughly 11/12ths of pledged players will undermine rather than reinforce.Not to be a buzz or anything, but I think similar thing is happening in the current CG system.
A million points of reinforcement isn't anywhere near as unusual as a million points of undermining.
(If anything this system is unusually undermined - it has about 1/11th of all undermining taking place so far this week, but only about 1/17th of all reinforcement)
