I see there is also a new (Old from 2017 ICC champions trophy with new name for public launch?) kid on the block making a bit of a splash alongside the world cup.
https://www.smartcricket.com/#section2Re bat speed discussion, I think this is more than that as they (BOTH) also have metrics for e.g.
- Max speed vs speed at impact which after all is effectively the very definition of timing (I think?)
- Follow through angle
- Angle relative to the ground at impact i.e. in the air or not which could be useful for a specific session trying to hit e.g. lofted drives etc.
- Max back lift angle ... a good indication of dipping the shoulder or dropping the bat (... and probably 'poking' at the ball / mistiming the shot)
- Whether the bat was lifted over middle stump or at an angle towards leg-side or offside (slip)
All the above I think from a practice session can provide a trend towards seeing if issues are being resolved, creeping into you game etc. without worrying about every individual ball.
My only real question with these things is the accuracy? The new mob claim 95% accuracy vs. high speed camera testing, but not sure for example when measuring the rotation of the bat face in the Z access (open or closed) that 95% is actually accurate enough for small deviations from 0 (meaning facing straight down the pitch) ... anyway ... am watching with interest the development of this as it takes the subjectivity out of critiquing every ball.
