I kept the speed sensor after acquiring a GPS module with the thoughts I could see clutch slip and lost traction at the rear of the kart. But if there were any of those conditions, by the time I saw them late at night on a race day or the week after a race it was way too late. Will keep relying on the best sensor in the kart, the driver. Thanks for your comments.
P.S. and it will be one less thing to remove and put back on during an axle swap. :)

I have a MyChron 4 and use the speed sensor. If using the Split Time or Time Compare is important then the speed sensor is needed. I found that the GPS data for the M4 drifted too much, even when comparing data from the start and the end of the day. The speed sensor old data (months old) could be overlaid with new data without resorting to shifting the time.
Aim says that the M5 is much better, I don’t know, as I haven’t tried one yet.
