OH my goodness that is a BEAUTIFUL BP. You absolutely should be proud of this.
So getting it to zoom in bursts means you need to adjust some numbers. I’d start with that base look up rate. You are probably moving very quickly and just hitting the clamp value very abruptly.
Just for your sanity, you don’t need those branches. You can drag “pressed” directly to “set” and sort of clean it up even further. It’s your call, but I figured I’d let you know.
