there are some smart guys working on GC. i don't know what the differences are between its calculations and WKO's, but it probably doesn't matter much anyway (for most of us). using it consistently and learning what the #s mean to

for setting FTP, since you have the NP (from a 60' race effort, i'm guessing?), use the 283w value and see how the workouts based on that feel.
