seedds 940947275d Frame step: probes back to 60 fps when the CPU is parked on efficiency cores or the GPU clock followed the longer hold ...

A game that waits out a hold of 2 vsyncs gets a lower clock on the iPhone (Tears of the Kingdom: 6% on performance cores at 1.6 GHz; Breath of the Wild: GPU 14.4 -> 25 ms with the same draws), so its cost never fits 60 again and the fit trial never fires. While either signal holds (thermal nominal or fair, Low Power Mode off), the frame step tries kmin after its hold-off, with 30 late frames of grace; a run at kmin under 8 s counts as a failed probe. t_fstep 39/39.
