After watching the first 3 sets, a few observations: 2. All the topspin jump servers for USA have abandoned it to the jump float. This is a pretty big change. I am a big stats guy for baseball, but haven't looked into it for Volleyball much even though it is my favorite sport to play and watch. So my stats question is... do the stats on serve effectiveness support the strategy of moving from full power topspin serves to jump floats? Random observation -- in Pro Beach Volleyball, I've noticed that the jump float (both low and high velocity) is replacing full power topspin serves for both Rosie and April Ross, who used to be bombs away a lot more than they were this past season. One thing I think I've concluded is that it really has got to be one or the other.... bombs away or an effective jump float... all those players who don't have either, but rather a soft-medium serve with some spin, might just as well walk under the net and place the ball in the opposing setters hands. I'm thinking that if a player doesn't have either, they should just pop it barely over the net and at least make the receiving team move around some.

One thing I think I've concluded is that it really has got to be one or the other.... a soft spiny serve is like placing the ball in the setters hands most of the time. Top spin serves have a trajectory that generally passers can track better and get used to it really has to be struck extremely hard and to the right location to be effective enough to get teams out of system, and they tend to be more high error. Float serves move in more unpredictable ways and are very flat making them harder to read and they can be more low error. We were not getting teams out of system consistently enough with the top spin serves I think, but we also kept whacking them in the net so we couldn't go on runs, so I think that's the main reason for the switch those two reasons combined. Now what do the stats say? I don't know. But that's just from what I've seen so far.

I have not stats to back this up.... My impression is that while you may get more clean aces from a bombing jump serve, a good jump float seems to cause more bad passes.... thus making it more effective (and probably a bit more consistent).

Well the outcomes probably vary by server. Women don't hit the topspin serve hard enough to make it effective at the international level. A rocket, low jump float is a much better option for getting teams out of system and scoring defensive points

You also have to remember that the FIVB ball takes the bite out of the topspin serve (more so than the NCAA ball), so even controlling for the level of receiver, jump serves will be less effective internationally.

That's a really good point. I'm not sure people realize what a big difference there is between the FIVB ball and anything that's used in NCAA or club ball. It's like an over-sized softball.

I know there's a natural tendency to overstate the differences between stuff like this, but I feel very strongly about that one being true.
