Agreed, but I would feel even more lousy continuing to charge them the higher rate while charging less to others.
You don't lower and raise your prices all the time, you do it once to determine the sweet spot and then you stick with that for a much longer time.
For me it was exactly as described: 2, evaluate, 2, evaluate, *2 evaluate -> go back one step.
At each step we had at most a few hundred signups processed before we made the decision.
The fact that it took as long as it did is only because I was skeptical, I should have realized much earlier that it can't cost too much to try, after all your signup rate would have to halve before you start to lose money.
