OK, so possible to get a reasonable idea with some work.
Although probably not in TB's case.

I would also add stance (wind resistance) and tyres as factors to consider. Mind you he's on about the heaviest, least efficient bike possible so if anything he's burning off more than he thinks.

I don't think you would need to take those into account as they would be fairly minimal differences in relation to any reasonable distance travelled
as long as you're not wearing a sail suit or something silly.

interesting.....
I thought I had heard that over coming wind resistance was one of the things that took most effort. I certainly noticed a difference when I took the drops off my commuter, but that may have been psychological.

Any wya I have no source, so it could easily be bollocks.

You're suggesting it
so it's most likely bollocks.
