Don, we do compete at the BIG $ bracket races, both locally and the Flings and I can tell you without doubt that no one that competes at these events cares if/what illegal devices maybe in use by some racers and the proof is that these races are typically sold out in less than 3 minutes! So all this talk about tree readers, down track position indicators, matty box, etc. is nothing but internet forum noise largely posted by racers like yourself that don't compete at these races. That said, running dead on, cutting .00x lights and taking a few thousands stripe is commonplace and no big deal in the year 2024.

That said, I do believe that ARC modules are being used by some with the Grid.
