A few days ago, someone posted a graph of their TT rating.

It was a pretty smooth curve, gradually edging upwards.

Then I look at my graph, and I cant help but wonder what's going on here...

Why do I take such a knock some days? Clearly, I can do many of the problems, because I always go back up, but some days I just dont see anything...
