I’ve by no means preferred the assault effectivity statistic. A part of that is my easy remark that (some) gamers will enhance their effectivity by avoiding errors, and in some instances avoiding spiking altogether. A part of it’s that I don’t think about a blocked ball to be an error. A part of it’s that effectivity misses plenty of info, ie what occurred to the remainder of the assaults that didn’t finish the rally. Partly it’s one thing in my soul that doesn’t like conservatism to be rewarded. I’ve proposed (and use each day) a completely different assault statistic.
One latest improvement in males’s volleyball has been the discount in assault from the proper aspect of the courtroom, ie the alternative.

Small pattern measurement, we are able to’t take that severely, one thing can’t be fairly proper. Let’s transfer throughout two columns to effectivity. That makes extra sense. A excessive ball in place 4 is far more environment friendly that the opposite positions. Case closed. Set all the things to 4, and let’s apply recycling.
However there’s something nonetheless nagging at me. Perhaps there’s some extra info I can use. (Spoiler alert: with Science Untangled there’s at all times extra info you need to use). Certain sufficient, there it’s. The Rally Win Fee exhibits lower than 1% distinction.
