I have an observation that does not make sense to me, for which I can think of no explanation. Perhaps you can help.
I have found over the years that reception from jump serves and reception from jump float serves is not the same. I don’t mean that the quality of reception is different, I mean that given a particular quality of reception, the likelihood of winning a point is different. In some cases vastly different.
For example, studying a team recently, I discovered that if the jump servers can force a negative reception, (i.e. only one possible attacker, basically a high ball attack) that team wins the point roughly 50% of the time. However, if the jump float servers can the same negative reception, the team wins the point only 45% of the time. The difference is even more stark with good reception without first tempo (i.e. both the outside can still attack a fast ball, a classic ‘2’ pass). In that case the jump servers won 43% of the time, but the float servers only 26%.
In each case the definitions are the same, the scoutman/recorder is the same, the team is the same, the figures are based on a whole season’s worth of data. The best I can come up with is that there is a difference somehow in blocking the two situations, but that is the best I can come up with.
To quote a popular figure from my childhood, “Why is it so?”
