New combination makes peak HP at 6800 and I expect will go through the traps at 7000+... won't know where it'll want to be shifted until it sees the track again

Checked my notes in The Wayback Machine and remembered I used to hit the 1-2 shift at 6200 and the 2-3 at 6500. Sounds comparable to new engine going 1-2 at 6500 and 2-3 at 7000.
