Can the TCU learning be reset this way?

[MikkiJayne]

Assuming this is resetting the dynamic shift program, I find it odd that it even needs doing tbh. Mine responds very quickly to changes in driving style, and even countryside - it knows when it's in Cornwall for example, and holds on to gears longer on the hilly bits and switches between cruising and hair-on-fire quite easily.

Edit - I wonder if its a difference between early and late software in the TCU?
