I tend to be agnostic about my warmup. Some people need a process to feel like they've got their **** together. I go for a much more general approach to get my legs moving and my spirit ready.
If I'm just racing one day, my rollers warmup often looks something like this:
1. 15+ min spin easy
2. 5 min high rpm/tempo
3. 10 min spin easy
4. 2-4x max rpm spinups, that wind up being about 20s on, 40s off
If I'm racing for several days in a row, I want my warmups to be long and easy. They often involve several sessions on the rollers - sometimes, that AM rollers session is just recovery Low gear, low intensity, medium RPM, for 30 or more minutes. Sometimes I'll do it for an hour or more in the morning, take a big long break, and then start a warmup for racing in the early afternoon. Sometimes I'll be on the rollers for 60 or 90 minutes total before really starting a warmup - just pedaling easy and getting the blood flowing.
Since I don't do events that require immediate jumps, if I don't have track time, it's not a huge liability to me to not have a fully loaded jump or standing start or similar as part of my warmup.
