Has anyone seen the case where speeds being displayed will spike up by nearly double for a refresh and then drop to zero on the next cycle and then return to normal? Mostly seems to happen for riders that are approaching the 60mph mark. Never really noticed it until I put the speed graphs onto the display, then had several in one night.
My guess is that its an artifact of the 7/sec display animation and the 4/sec hardware output somehow lining up.
This will go away with the new firmware (ETA a month or two). But if you look at the ruby terminal, you will see bad data coming in and screwing up the parsing when that happens.
