Gear and stats at the end.

3 burst p1, and then 2/2/2/2.
Timer wise, it was very close, but I did not pop ror off cooldown perfectly for all my bursts, so all those delays added up and gave me very little time for the final (11th) burst. And obviously, the chain deaths towards the end.

Most of the room for improvement (in the sense of min clear) would be p1 uptime; if I had to guess, I think I was like 10% fd overstatted to comfortably phase p1 before 4th burst comes up. Having WH buff would also make a 3 burst p1 much more practical at lower damage.
As for p2, 2 bursting each segment seems fairly trivial. I tried phasing through segments without waiting for burst, but it changes nothing from my testing (except 2-4). You might as well just wait bursts to make half of your p2 bursts "free."

Then, as I mentioned, eliminating the minor delays in subsequent bursts would give more time for the final burst in 2-4.
