As far as I could make out from that figure, it is not as per my post.

Wondering whether KT pas level is actually controlling battery current rather than motor current, like @Sparksandbangs is trying to achieve. It would be interesting to see motor phase current along with battery current & speed for any specific pas level with KT controller.
I am confused too. It seems by the name of the jpg file, the plot that saneagle posted in #50 was made with the speedict kit, not a KT controller.
Also, unless I am mistaken, if your chosen assist level means that the controller will aim for example 5A battery current and you slow down, you don't need all the 5A, you'll need a lot less. What would the controller do?

The recording device is basically a wattmeter with GPS or speed sensor and data logger. It fits between the battery and controller to record current, voltage watt-hours, speed, etc. The problem with phase current is that it's very nebulous as far as the rider is concerned, so there's no need to be interested in it. Most people can't even understand what it is. There have been countless discussions on ES about it causing everybody to end up scratching their heads. On the other hand, the rider can see and feel the direct link between battery current and torque so that's the only one I'm interested in. Phase current is just some theoretic calculation. It never has a real value because it's pulsing in alternating directions, sometimes square wave and sometimes pseudo-sinusoidal.
