You think that trips made outside the peak are going to be *slower*?

Okay, you made a trip in the rush hour going against the traffic, and
claim that it was made at a good speed. You quote 45 minutes from the
Green Man to the Albert Hall. Fine, that's a fact I can accept.

The same journey in the other direction at the same time (RAH - Green
Man) would probably take almost two hours. That gives an average time of
90 minutes or so to cover at most 10 miles.

On my side of town, I regularly travel from Heathrow to hotels in the
centre of town, and travelling with the main traffic flow in the rush
hour takes about 100 minutes (Using all available bus lanes), where
travelling against it takes 40 minutes or so without using a bus lane.

On occasion, even outside the rush hour, the trip either way can take
well over an hour.

In my experience, bearing in mind I drive in London at all times of the
day and night, the TfL average speeds I quoted earlier in the thread
are, if anything, optimistic.
