Feature Suggestion: Swing Speed (and Path?) Only Mode

A really useful feature of a handful of launch monitors on the market is the ability to measure swing speed without hitting a ball. This would be a great feature to add to the R10 for anyone doing overspeed training. Even better would be if we could get swing speed, tempo, and club path measurements. If the R10 could provide that data without having to hit a ball that would immediately make it the premier device on the market for anyone doing overspeed training.
