  • Comparing Penn State and Low Country Volleyball Club – Volleyball Coach Chuck Rey | Volleyball Blog | College Volleyball Coach
    for Nationals in Miami I received the stats from the team s championship weekend we have a parent keep stats and just for fun compared them with the offensive stats of the 2008 Final Four Teams Penn State Stanford Nebraska and Texas I was testing a coaching theory of IPE read my What is IPE blog if you are unfamiliar with this concept Here are my findings Team Kill Efficiency IPE Hitting PSU 0 529 0 874 0 390 Stanford 0 425 0 888 0 337 Nebraska 0 411 0 858 0 324 Texas 0 453 0 882 0 349 FF Average 0 454 0 875 0 326 Low Country 0 433 0 872 0 311 Final Four IPE average was 875 LC s IPEwas 872 better than Nebraska and almost as good as Penn State Kill eff LC s was 433 better than Nebraska and Stanford Hitting LC was 310 Nebraska was 270 Stanford 314 Texas 335 PSU 380 I think at any level the game comes down to efficiency and execution Low Country proved to be efficient and executed at a championship level Share this Click to share on Twitter Opens in new window Click to share on

  • What is IPE? – Volleyball Coach Chuck Rey | Volleyball Blog | College Volleyball Coach
    Stats are used to provide trends of players and teams as a guide of strengths and weaknesses The Hitting IPE stat is one stat of many that breaks down hitting percentage Hitting percentage is a combination of error and kill Both parts are essential to a hitter and a team s success For example the average Hitting IPE of the four final four teams was 875 This number can become a team s season goal In addition to this goal the average kill percentage of the final four teams was 0 455 with one team far exceeding this average of 0 529 care to guess which team A combination of IPE and Kill can be used as a guide for players and teams to measure their level of success versus the competition If a team has an IPE of 0 875 or a goal of 9 out of 10 attempts in play PLUS has a kill of 455 or 5 balls out of 10 attacks as kills the team has a greater chance for offensive success Share this Click to share on Twitter Opens in new window Click to share on Facebook Opens in new window Click to share on Google Opens in new window Related Drills hitting in play efficiency IPE kills Mick Haley Mike Hebert Penn State University of Minnesota 2009 02 26 Chuck Rey tweet Previous To err is human Next Patterns 12 comments Coach H August 7 2009 at 10 06 pm I m not one to spend a lot of time trying to sugar coat everything and tell everyone I love them if I don t BUT in my opinion the main advantage of IPE is that you can set a goal If you set goals for errors it s seems to be more of a pass or fail system Let s say you want less than two passing errors from a certain player and get their 3rd error on the 3rd serve The player feels as if they have failed With IPE your goal is not defined until the game is over Let s assume you want a hitting IPE of 700 or better If you miss your first 3 you still can have hope that you will get 7 more sets and keep them in You can keep striving to achieve that s what I really like about the system Coach H August 7 2009 at 3 06 pm I m not one to spend a lot of time trying to sugar coat everything and tell everyone I love them if I don t BUT in my opinion the main advantage of IPE is that you can set a goal If you set goals for errors it s seems to be more of a pass or fail system Let s say you want less than two passing errors from a certain player and get their 3rd error on the 3rd serve The player feels as if they have failed With IPE your goal
