I too like your charts and agree with your reasoning. One thing I'd do before bending sensitive switches is check that the switch dogs for the relevant Score Motor switch stacks are in the proper (Short or Long) positions. That could affect the relative timing of the pulses too.

I've thought about this some too. This is essentially be a circuit simulator which is pretty standard in the electronics world. There are even free simulators available. The problem is that to my knowledge most simulators don't know about relays, steppers, score motors, etc. so there would be some work to do to add these devices. It's a project that's on my 'some day' list.
