UNIVERSAL TURBOSLIDE
I'm glad Jim Antaki got in touch with you about your development to the Turboslide concept. He's a busy man and can be rather unresponsive.
SLIPSLIDER
Your video demonstrates well what I tried to explain to Richter players about the SlipSlider in the past: just put it in one position and leave it there, then explore!
Here's a video of my MK3 model demonstrating that approach, with charts explaining the logic behind it:

It was intended for good players who were familiar with the Richter layout throughout the whole range, showing how the SlipSlider concept could be understood as simply moving familiar chunks of the Richter scale to new places. However I failed to grasp that most found this massively confusing...
Your video is about one of the shifts, where the top octave now has a regular-breath pattern instead of reversed. In a sense as a relatively new player you have an advantage, because you don't have years or decades of muscle memory to overcome. Long-term Richter players seemed to find it so disorienting when the SlipSlider gave them their familiar breathing pattern from holes 3-6 but placed it an octave higher in holes 6-9.
No matter that it's EXACTLY the same note pattern as the lower range they know so well, because it was now in the area where they automatically switch to a reversed breathing pattern, they literally couldn't play!
I was amazed, quite frankly... But then I'm so used to switching between tunings from doing it all my career, that I clearly didn't grasp the power of the entrenched muscle memory the pure Richter guys have developed.
Hopefully younger players will realise the beautiful extra expression and chromatic ability the SlipSlider can offer and start using it from an early stage, before their brain circuits get hard-wired.
Your enthusiasm for this concept is refreshing
