There are some guys who can ride a cat5 crit off their wheel. They tend to have numbers commensurate with the cat 1-2 section of the e-wang when they are 5s. 290 is below 4 w/kg in this case, and in all likelihood the actual FTP number is lower, so unless you find some other way to go that much faster than the pack, it's time to be more realistic about what your relative strengths are.
