You shouldn't have any problems then. None of this is rocket science, but graphing takes a little time and helps with understanding how/when things are going to happen and, especially, how the downshifts are related to the upshifts.
I think, knowing what I know now, I'd probably lower the TM in 20% intervals instead of 10% intervals, especially the ones at the higher speeds and higher gears. The lower gears and speeds will "feel" the lower TM a lot quicker than the others. You'll see when you give it a go.
