PDCA and Class One through Three Sectional ratings March 1, 2021

 Anybody know what PDCA stands for?  No?

I will tell you....  PDCA stands for Plan-Do-Check-Act.  It was coined by Dr. H. Walter Demings and used in his work to assist the Japanese in the 1950s to improve their electronics quality.  Some of you may remember the early transistor radios from Japan that lasted about two weeks before they broke?  Probably not, but now everyone gets their electronics from Asian manufacturers.  The Deming Wheel, or Deming Cycle, this integrated learning-improvement model was first introduced to Dr. Deming by his mentor, Walter Shewhart of the famous Bell Laboratories in New York.

What does this have to do with boys' and girls' basketball ratings?  Well, when starting a project, you PLAN out what you want to do, you DO it, you CHECK what you have done and then you ACT accordingly.  A simplistic version of this is "measure twice, cut once".

When I built the rating model, I had to plan out spreadsheets with 500 plus teams and put in formula names for each team.  I started the ratings and occasionally, checked to see if my ratings were solid or not.  If not, I double-checked scores, added more results, and posted new results.  If I got feedback on a team, I used that to act on new ratings.  

The goal of a PDCA cycle is continuous improvement.  Every PDCA cycle should result in better results.

Well, lately, with so many game scores coming in, I have built some reporting tables and did the DO-DO cycle.  I did not check the table formula and am now finding mistakes.  

Or, rather, readers are finding mistakes.  I received a message from a fan of Maryville girls who pointed out that Maryville was better than Chillicothe.  I knew that and if he read 810Varsity he would see that they are rated better.  But my district table was messed up.  Instead of a neat little formula for Maryville in their rating cell, I had a number.  A low number.  PDCA?  Not!!

So I apologize to all Maryville fans and here are the Class One through Three Girls and Boys ratings.  Hopefully, you won't find more mistakes.  LOL

Missouri Boys class one high school basketball ratings 12/22/2020

 Class one clearly belongs to the vaunted South Iron squad.  The only thing keeping the Panthers from winning a state championship trophy this year would be the pandemic, which could, unfortunately, end the season at any time. Last year, Dora "upset" the Panthers in the sectional game.  I honestly believe that South Iron would beat Dora this year, except that Dora was moved to class two and Coach Luna and his four sons are now in Viola Arkansas and Isaac Haney transferred to Kickapoo.  South Iron's coach Dinkins has taken on an aggressive schedule with Vashon, CBC, Cardinal Ritter, Helias, and several other top-rated schools in class five and six.  Hats off to the Panthers for taking on the big dogs. In class two, Dora will be lucky to win ten games.  I don't know the specifics on Rick Luna's firing last spring but the school board's kids are getting a lot of playing time this season with the Luna family in Arkansas and Haney gone to Kickapoo.  Viola, ...

Missouri Boys High School Basketball Ratings - All Classes 12/07/2020

On this 79th anniversary of Pearl Harbor Day, let us remember the brave men and women who gave their lives for our great country. I posted Pre-Season rankings for Boys and Girls Missouri High School teams in mid-November.  A bunch of Thanksgiving and early December tournaments have provided me with data to populate the statistics for a robust ranking.  Robust it is not.  I won't have a good handle on team ratings until the end of December when most teams should have five or six games under their belt. I am still waiting for MSHSAA to post classifications and district assignments, so I will not post class rankings until that info is known. The other day, I noticed that the esteemed Earl Austin, Jr. had apologized on Twitter for omitting a great performance by an up and coming sophomore, after an outstanding performance.  I didn't think he should need to apologize.  When you think about all the kids and games he is watching on the tube, there is only so much that ...

VPS as a metric for winning seasons - March 29th, 2021

Image
  Premise:   If VPS (Value Point System) directly correlates to a team’s winning percentage, why not use it as a metric to drive team improvement? What is VPS?   VPS stands for Value Point System.   It is calculated by adding the points and rebounds plus two times the Assists, Charges taken, Steals and Blocks and dividing that product by the Number of Free Throw misses plus two times the Field Goal misses plus Fouls and Turnovers. Most players focus on two things, scoring, and sometimes, rebounding.   Kids grow up with parents asking, “how many points did you get today”?   The emphasis is on scoring, but scoring is only part of the game.   If more emphasis was placed upon passing, shot selection and defense, individuals would be more likely to contribute to a team-oriented game rather than accumulating points. The best player on the team is not necessarily the top scorer.   The best player of the team is the player who gets high percenta...
