Note that the number of rays needed to stumble upon a caustic is even larger - unbiased path tracing is NOT good at this and Cycles isn't really set up for caustics. Yes it can find them, but not in a few minutes, or sometimes not even in a few hours.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
