thanks--that sounds like a great TT set. Yesterday's success has definitely showed me I'm ready to try some higher tempos, so I'll try it later this week and see what happens.
One interesting thing: after doing the TT pyramid slower and faster back to tempo 1.2, I dropped from 15 SPL to 13. When I continued increasing speed to 1.1, 1, 0.9, I held 14, 14, and 15 SPL. So at 0.9, I hit 15 SPL, which is where I started at a TT setting of 1.2.
So, my SPL doesn't increase with faster tempos as much as I expected. As my neurons get used to faster tempos, I'm betting I'll hold SPL even better at these fast tempos. Which is all very exciting!
