Re: how about this code.

Stephen,

You can see I attempted to reformat your code to make it more readable. Now you can see how your code nests...

I agree with Mark. I'm not worried about you missing an encoder ping but rather that you will get multiple hits at one ping.

You should consider implementing a state machine. Do you have a mentor on your team (what team are you with anyway?) who can teach you what a state machine is?
