has anyone worked out how to change the end points of the servo via telemetry?

I know there are other methods to slow down the servo based on throttle. I do this now.
what im looking for is to contract the end points when speed is very high to smooth out high speed turning.

C-mix will allow you to create a ratio between st, th, aux1 and aux2.
this is great for a car that jumps to the right or left on throttle on accel or deceleration.
I think I understand how it works and im using it.

Curve will allow arc, exp, ...

t-mix allows telemetry data to compensate something like a cold motor that needs a high idle until the temperature comes down.
