Why are the HR and MR FirstSwingExcursionAngle overwriting each other in the command window?

If we run them seperate it works fine, but if we make a combination of HR/MR in the code it does not.

This works fine:

We don't know anything about your files, but I don't think you want to combine your j and za for loops the way you did. I think you want to keep these as two separte loops.

Also note that in your calculation of sumMR you are using t0HR instead of t0MR.
