Marty,
Do we really have to count transports as a half step? I normally use a lot of them and that would force my step count up.
If we do have to count transports, how about only 1/8th or at most 1/4th?

Don't be afraid, come along with the very very difficulties. In this one, one of the "6's" in column 2 makes it a one stepper.

I suppose at this point in the process it would be appropriate to propose a compromise at 3/16.  |
