I understand. We are making the same point: It's all about the computer program or algorithm.

Folks ask well why? Why can't I hook it up to my TH350 somehow with a CO2 bottle like Steve Strope did or with a linear actuator motor? It's still just a hydromechanical transmission. All you accomplish under those circumstances is to replace the motion of your arm, the floor shifter and the shifter cable. You are still operating a "dumb" transmission. If you feed a carburetor with an electric fuel pump, can you call it fuel injection? No. You need a computer, sensors and a map (program or algorithm)


T/A,
I've run it at the track and used it at autocross. No road course yet.
In the 1/4 manual mode is better when wheelspin is present. Otherwise the computer sees mph increase and prematurely upshifts. In a perfect world, automatic mode would be better. But when traction is limited or you need to overcome a fuel stumble or some other variable, I'll take a paddle shifted manu-matic over any other option.
When autocrossing, driver's typically just leave their transmissions in 2nd gear. The course is slow and tight enough that shifting is cumbersome and unnecessary. But with paddles located on the steering wheel and ultra quick manumatic shifts, it is possible to paddle shift between 2nd and 3rd gear. Downshifting back into 2nd induces engine braking which can be beneficial on certain corners. I have a separate auto-cross program that I can load. Has a little extra line pressure built in and lower downshift prevention parameters.
