I've spent a few days now dialing in some tracking with Mocha, and what tends to look best for what I'm doing is just PSR stabilization, though I'm roughly split between whether I like the results better with or without the scale being applied.
Is there a way to apply just a percentage change? Use a null with script somehow? Or maybe just put script into scale parameter that says take the scale being input, and divide difference between it and 100 by a user supplied constant? Does that sound right? Is there maybe a built in way to do this I'm missing?
