You have chosen the UNIQUE speed ..... and the ONLY one which will fit the description you have chosen...
20kph of slip AT 20kph.....
Why is it a 'special speed'....? because it's the ONLY speed at which the SAME piece of rubber is presented as the 'contact patch' for the WHOLE event..... At EVERY other speed with a '20kph slip' (even ones I DIDN'T choose), a NEW piece of tyre (contact patch) is presented every instant!
At 20/20 (shorthand), the tyre CAN 'know' what is happening becasue it is the ONLY speed at which that event occurs.....
However.... at all OTHER speeds.... the tyre CANNOT 'KNOW' it is rotating at the 'gold standard' of 20kph slip at 100kph or at any OTHER speed which is NOT the 'gold standard'. For the contact patch..... ALL those speeds at 20kph slip 'look' IDENTICAL!
Look closely at ANY two OTHER speeds and TELL me how the contact patch is presented with ANY different 'factors' in what it's asked to do!
There IS no difference from the contact patch's 'point of view' EXCEPT how rapidly and/or frequently it's being replaced by a DIFFERENT contact patch!
It's THAT which hold's the key to why 'semi-lock' works.... we are presenting a contact patch for period of time BEFORE the contact patch temperature can rise ABOVE it's tolerable working temperatures. Before it exceeds that temp, we replace it with a FRESH-COLD piece of tyre!
