I’ve by no means favored the assault effectivity statistic. A part of that is my easy remark that (some) gamers will improve their effectivity by avoiding errors, and in some circumstances avoiding spiking altogether. A part of it’s that I don’t take into account a blocked ball to be an error. A part of it’s that effectivity misses quite a lot 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 different attack statistic.
One latest improvement in males’s volleyball has been the discount in assault from the precise aspect of the courtroom, ie the alternative. That is particularly obvious in excessive ball conditions the place in lots of groups the opposites position turns into to cowl for the place 4 attacker who tries to recycle, after which perhaps get a quick ball after that. The logic is that the excessive ball assault from place 4 is extra environment friendly and extra manageable. And I believe feeling that outdoors hitters are extra expert and subsequently extra capable of be environment friendly and handle excessive balls.

And that’s what we notice instantly that we see that prime balls from place 1 win essentially the most factors outright. Small pattern dimension, we will’t take that critically, 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 every thing to 4, and let’s apply recycling.
However there’s something nonetheless nagging at me. Possibly there’s some extra info I can use. (Spoiler alert: with Science Untangled there’s at all times extra info you need to use). Positive sufficient, there it’s. The Rally Win Price exhibits lower than 1% distinction. The place I select to set the excessive ball makes just about no distinction to my probability of profitable the rally. Assault Effectivity lied.

Possibly it did, and perhaps it didn’t.
