What is Back Stroke Length?

Back Stroke Length is the length the putter face travels in the Back Stroke from address to the top of the Back Stroke. Back Stroke Length is measured in inches and is one of the 3 main elements of distance control, along with Stroke Timing and Stroke Speed. A best practice for this metric is to ensure the putter face is close to the back of the golf ball at address before starting your stroke.

Think of the Blast sensor as a ruler for your putting stroke.
