The curve is anchored to 1 August rather than rolling, and that deserves saying out loud, because starting a performance chart where performance improved is the oldest trick there is. Something specific changed at the end of July: the model the analysts run on began grading its own conviction far more strictly, the buy rate fell by about a third, and the hit rate roughly doubled. We can date that boundary exactly and we can only partly explain it, since the desk's exit machinery matured across the same weeks and the two causes cannot be separated on the evidence so far. Both are written up in why the desk stopped buying. The bot on either side of that line is not the same bot, and splicing the two into one curve would describe neither.

Each week on its own, so a good fortnight cannot carry the story. The desk beat the benchmark in 3 of 5 weeks. Weeks run Monday to Friday and the first one starts at the window anchor, so it can be short.
