C-bet drought

[stuartharris]

First, a confession. I've been short-stacking for most of the last 4 months. Doing so, I was able to play at higher levels than I should have been playing and turned $50 into $550 in a little over 2 months. I've been in freefall for most of the last 6 weeks and have finally had to admit that always been short stacked both limits my options and is keeping me from learning to play poker. So I'm dropping way down and playing big-stack poker for lower stakes. With all of that as a backdrop, I was still amazed when I found this last night. This is a graph of what happens when I c-bet on the flop:


What does this mean?

Is it just a natural correction, where both my good run and bad represent small samples?

Is it evidence that NL10 and NL25 players have no idea what to do against a cbet, but NL100 players do?

Is it evidence that my stats caught up with me? that, at NL50 and NL100, there are more regulars who are likely to observe what I'm up to?
