As an aside, 250 watts is probably as high, or perhaps higher, than
the usual recreational cyclist normally produces.

My health insurance says 2 watts per kilogram body mass is a healthy,
above average value. So a normal recreational cyclist is likely to have
a sustained output on the order of 100W (typical female, 50kg) to 150W
(typical male, 75kg).

I'm nearly 75 and 6'4" and have fattened up to 190 lbs with something of a small roll around my middle and can sustain 350 watts for over 10 minutes and a continuous 250 watts. Since everyone on two wheels seems faster than me I have to wonder about that claim.

Me, too. Skip the formulas and get a real power meter -- assuming you're that interested. Stages. https://store.stagescycling.com/stages-power-meters It's the best (product placement for my son's employer). Personally, I have zero instrumentation, although I do swipe data from my riding buddies and then mark it up 25% for age and inability.
