I'm totally okay with today. It was more about probing with new approaches than getting results. My overriding objective for the season has been to learn to race, and this is all part of it.
Tomorrow, I'm going to go ahead and try the 4-5 again, and stay far enough up to hopefully avoid the accordion and feel more comfortable. On the 50+, I'll try the late, 2+ laps to go, attack.
