[helter skelter]

Thanks. The numbers make sense.

I was just having trouble wrapping my brain around why the 2 events were so different, where post-flop, the probability that my opponent has a flush draw was less than half the pre-flop probability that he would flop a flush draw.

I had to think about it a couple hours to get the light bulb to turn on. It is not glowing brightly, but at least I can see shadows.
