I've just tested the latest version the the Hybrid V3. The updates had nothing to do with improving accuracy – they were more of a practicality thing to be easier for real casino conditions. It made it easier to do more testing against live spins from my wheel. Basically the accuracy has worked out even better than I hoped for. Reliability under normal conditions is perfect.
When the camera wearer is moving around a lot, I can see some room for improvement but it is not essential and can be done later. As for the final part before it can all be used, this is now about 30-50% complete. The programmers are still working on it together.
