 | Poll and Tutorial: Serving (SRV) and Serve Receive (RCV) Posted by |
(photo credit to ME; this is Josh passing a serve from an Edwardsville High School match in 2019)
This is a draft of the Serving and Serve Receive (also known as Passing) Tutorial I will add to the "Algorithm" (or create a new menu name) at the top menu.
Max spent a lot of time on winter break from college going through code and putting together very specific percentages based on interactions including:
1) Serving/Receiving (SRV/RCV)
2) Setting (SET)
3) Attacking - including blocking and digging (ATK, BLK, and DEF)
These form the primary areas of gameplay. Our process for this was: a) Max created some big Excel spreadsheets and b) Steve read that and provided the summary below. Thanks Max and Steve. There's also a multiple guess poll at the end (10 RP for correct responses; 5 RP for trying). With all that said, here's Steve's summary:
==============
Serve and Serve Receive Algorithm with Examples
The first part of any point is obviously the serve and how the receiving team deals with it. There are ONLY 4 players involved in this interaction:
1. Serving Team's Server
2. Defending (Receiving) Team's L
3 & 4. Defending (Receiving) Team's two Outside Hitters (OH)
Each serve and pass is rated from Excellent (3) to Bad Terrible (0) and depends on players' SRV and RCV skills ratings and a random number from 1 to 100.
Serving Rating Key
3 - Excellent
2 - Good
1 - Poor
0 - Terrible
Serve: The chance of an excellent serve is 65% at SRV 20 and decreases by 2% per skill level to 27% at SRV 1. The chances of good, poor and terrible serves are more complicated so only a few examples will be given.
An excellent serve is always in, a good serve is out 25% of the time, an poor serve out 40% and a terrible serve 50%.
The chances of each serve rating based on these skills are.
SRV 18 : 61% excellent, 32.8% good, 6.2% poor, 0% terrible
SRV 14 : 53% excellent, 33.8% good, 11.3% poor, 1.8% terrible
SRV 10 : 45% excellent, 33.0% good, 15.4% poor, 6.6% terrible
Receiver: The player that receives the ball depends on the specific serve rating for this serve (0-3).
Excellent : 45% worst passer (RCV), 40% second best passer (RCV), 15% best passer (RCV)
Good : 35% worst passer , 35% second best passer , 30% best passer
Poor: 15% worst passer , 25% second best passer , 60% best passer
Terrible: 100% best passer
Pass: the pass rating depends on the serve rating, the server's skill (SRV) and the receiver's skill (RCV). A few examples:
Pass Rating Key
3 - Excellent
2 - Good
1 - Poor
0 - Service Ace
Excellent serve: Server 18
Receiver 18 ; 49.7% excellent, 25.0% good, 14.9% poor, 10.4% ace
Receiver 14 : 44.8% excellent, 24.7% good, 16.5% poor, 14.0% ace
Receiver 10 : 40.0% excellent, 24.0% good, 17.7% poor, 18.3% ace
Excellent serve: Server 10
Receiver 18 ; 56.1% excellent, 24.6% good, 12.8% poor, 6.5% ace
Receiver 14 : 50.6% excellent, 25.0% good, 14.9% poor, 9.5% ace
Receiver 10 : 45.2% excellent, 24.8% good, 16.7% poor, 13.3% ace
Good serve: Server 18
Receiver 10 : 48.0% excellent, 24.9% good, 14.8% poor, 12.2% ace
Poor serve: Server 10
Receiver 18 : 86.5% excellent, 11.7% good, 0.9% poor, 0.9% ace
Terrible serve: Server 18
Receiver 10: 57.3% excellent, 24.5% good, 9.5% poor, 8.7% ace
The Pass rating is then used to determine how good the setter does based on his rating (which we'll review in the next tutorial).
If you want to see more details on how skills interact with each other and the percentages download the spreadsheet here and look for the "Serve Rating" tab.
Readers Comments
As a quick follow-up, please ask questions about this post. Before I add the info as the "official" info/instructions/etc I'd like to see if you have questions/clarifications so we can tweak info as needed to help us all make good use of it and understand it better...
What technique is Josh using there? We were taught to put one thumb i(I'm right handed so my left thumb) in the other hand's palm and wrap the left fingers under. Has Josh got both thumbs showing?
I was shown to put hands and thumbs side by side. I'm not sure the purpose of it, but I think it has to do with being able to engage and disengage faster, basically takes more time to "interlock" the thumb. The time difference is extremely small, but given the reaction time needed, it may make a difference in being able to pass a hard-driven ball.
I was told that hands had to be interlocked in some way or you'd get a foul for a double hit. Josh's hands are locked however with his right fingers under his left hand. . The only reason I can think of for the locked thumb is it gives a slightly wider area to play the ball.
I was taught to place the hands open palms up as if expecting to catch a large watermelon dropped from a tall building.
Things to edit.
In Receiver it says servers (SRV) rating. SRV shouldn't be there as it's his skill and it's the 0-3 rating.
For s good pass the percentages add up to.90%. Probably a fat finger typo on my phone.
Something I've found in the link Al provided is the overall chance of the serve being in. So using 18, 14 and 10 we have
SRV 18 - 89.3% in
SRV 14 - 86.1% in
SRV 10 - 82.3% in
You might have seen in the rules that the random number is 1-100 so how do we get decimal chances? With most of the chances there's a roll to see if excellent (SRV 18 is 61% above). If not excellent then another roll to see if good. If not good then another roll...
