Actually, I think Xsight is a better fit. It lets you specify durations, so each max and min becomes one step with a press-and-hold duration rather than 20 steps.

I'm a big proponent of JP1, and such a thing is also do-able with either custom protocols or recursive macros, but Xsight is easier. The 12G is about equivalent to a 510 device-wise and is about $30.

However, first you really need to take a step back and find simpler solutions for your macros. 80 steps is ridiculous. Surely there are some discretes or different strategies to achieve the same thing much more easily.
