There seems to be a mismatch in the numbers displayed.

After a bike session the summary was:
Power average: 74 Watts.
Time taken: 9 minutes.
Energy used: 50 kcal.

The above energy figure would equate to 333 kcal per hour.
But 100 Watts is only 86 kcal per hour!

The mismatch is so enormous that I feel I must have missed something.
I would be grateful to any physicist who can shed light on the figures.

You have missed the fact that ,mots people know how long 9 minutes is,
and roughly how much power a cyclist produces.

They are also familiar with how many calories they had for breakfast.

But not the conversion between them

So to the average punter 'hey I pedalled hard enough to light a 60W
lightbulb, and burn off three English breakfasts' will make them feel
good and come back.

To tell them they didn't even burn off a slice of dried toast is simply
bad salesmanship.

Cui Bono?
Follow the money.
