Mark from At Home on the Court once posed a question on Facebook. It went like this:
What does number of transition attacks divided by number of serves measure? If anything.
After a bit of discussion, Mark made the following clarification:
So now I have removed service errors and direct block points. I am left with transition attack attempts divided by number of times the attack gets past the block. What am I measuring now?
So we have this formula:
Transition Attacks / (Opponent Attacks – Blocks – Hitting Errors)
My response at the time was to say that broadly speaking you are measuring dig %. After all, you must dig the ball to get a transition swing. If you consider Transition Attacks to be something other than simply playing the 3rd ball over the net, then you are effectively deriving a “good” dig %. The first requirement of attacking back at the opposition is a settable dig (or, in theory, hittable on 2).
I’d be curious to hear what you would say in response to Mark. Beyond that, though, I wanted to point out the importance with regards to statistics of actually understanding what you’re measuring. It might not be the same as what you think you’re measuring.
