Comparative SRM/PT on same bike

To this you have to add the loss of power through the drivetrain for the PT, ie the PT says you are doing 309W at the hub but you can assume from this that you are actually doing 313W at the cranks, whilst the SRM says 300W only at the cranks.
Do we agree?

The jumping figures for the SRM seems to be well documented too.

Gutted - I'm too old. I would try lying, but I'd never get away with it. My age is written all over my face
