Full disclosure - I am one of the new Sparx Brand Ambassadors.
We have a Zoom call with Russ on Thursday. I will ask about how the bluetooth actually benefits the end user. Let me know if you have other questions.

I am interested in automated calibration. Thats the way to get the machine perfect and this might be a step in that direction.
