No problem, glad you found it helpful. I know that others are still having success with a traditional cleat position too, so it may not be ideal for everyone. I moved my cleats back some time ago at the same time I started experimenting with larger gears. I don't have a power meter, so can't really quantify any changes like you can, but this might be part of the reason I seem to be going quicker these days.
What did your coach think of this idea?
