FXS Prop Desk, one thing in my own log surprised me about the lower target. A 5% goal looks so close that I traded it faster, and the ticket count shows it.
Across my last six challenges I averaged 2.4 tickets per session in phase 1. In the first week of phase 2 that jumped to 3.8, then settled back to 2.6 in the second week once the novelty wore off.

The illustration shows those three averages side by side. Most of my phase 2 losses sat inside that 3.8 week, which is also where the restarted buffer is thinnest.
So the maths and the behaviour pull in opposite directions. On paper a 5% target against a 10% maximum loss is easier than 8% against the same floor, yet the easier target invited more tickets.
My fix is a hard cap for the first five sessions of phase 2, set at the phase 1 average rounded down to 2. After that the normal plan applies.
Did your phase 2 failures cluster in the first week, or spread across the whole phase? Of my six phase 2 runs, the worst drawdown started in the first week in four.
