I'm pretty sure Eddy wasn't running a Powertap or an SRM. Do you actually have any way of proving your 385 number? Or is it some sort of imputed number (in which case there's all sorts of variables). Or are you just throwing numbers out for the heck of it?
I think they measured it, perhaps even retrospectively, by refering to the amount of calories burnt. Ie if you burn 1000 cal in an hour (1000 * 1000)/(60*60) = you'll have put out around 277W/hr. It's a rather primitive method, and some more knowledgeable person can probably fill you in on that.
I just found the following figures though, produced by
Sabino Padilla, the former Banesto doctor I believe. It's re the hr record.:
Cyclist - Distance - Date - Mass, kg - CX, m2 - Power, W
Merckx - 49.432 - 10/25/1972 - 72 - 0.2618 - 380
Moser - 51.151 - 1/21/1984 - 76 - 0.2481 - 400
Obree - 52.713 - 4/27/1994 - 71 - 0.172 - 359
Indurain - 53.04 - 9/2/1994 - 81 - 0.2441 - 510
Rominger - 55.291 - 11/5/1994 - 65 - 0.1932 - 456
Boardman - 56.375 - 9/6/1996 - 69 - 0.1838 - 462
When normalized for power to weight ratio, you'll find the following:
Cyclist W/Kg
Merckx 5.3
Moser 5.3
Obree 5.1
Indurain 6.3
Rominger 7.0
Boardman 6.7
It must be mentioned that Moser and Merckx rode at 8000ft in Mexico City, which would account for some loss of power (estimated 10%), so their normal sea level power would be 5.8 W/Kg.
I do think improvements are possible over the span of 40 years, with better training, more specific training, better nutrition, better equipment (less power loss) and aero positions, but I obviously can't say what lies within reach of human capabilities.
