So, the physics is off on your estimate. You're putting out less than you think at 22mph, and can thus go longer.
In either case without a good meter, it's still guess work. The hill is closer to reality, the steeper it is. But you'd still need to lookup the CRR of your tires. Flat? Nah. It won't work out without one.
really? i’d like to see some data on that, the sources i’ve used mostly agree with this. 240w = 20-22mph:
obviously i am using a power meter for the ride data, not just making it up. of course it could be off, but it matches the bike calculator estimates almost perfectly for slow climbing, which is a pretty simple exercise:
