Thanks! I wasn’t aware.

192 ms with ROCK2 vs 495 with KenCarp47 with NLAnderson. You’re a wizard!

Edit: the oscillatory \beta problem is now down to 10.74 s from 47s. Just wow.

Wow the perf gain is amazing. Once you are done with this and if you have time could you make a tldr summarizing this thread?
