Why would you not want it to show up?

I think it will show up regardless, since you were there and a registered player. You could have gotten points for entering classics if you wanted to.

Hilton - If IFPA endorsed events include divisions of play that are ineligible for WPPR points, we still include those results as part of the IFPA Rating system. Because the IFPA Rating system is a player-vs-player metric, the results in the B/C/Jrs/Srs divisions are good data for adjusting the IFPA Rating to more accurate representation for each player. In turn, that IFPA Rating is used in the formula to determine WPPR point value when those players end up participating in WPPR eligible tournaments.

Yes. Your rating went from 1476 to 1264.

oops

The job of the IFPA Rating is to use as much tournament data as possible to determine what your skill level is (similar to chess). Based on your B-division result, your record was 0-100-6.

Bowen surely knows how the Glicko algorithm works better than I do, but pretty much every loss against those 100 players lowered your IFPA Rating by some small amount. In total that performance adjusted your IFPA Rating by the 200+ ratings points.

A new players starts with a provisional IFPA Rating of 1200. Based on your 5th place finish at the 2012 Waun-a-Pinball Tournament, where you had a record of 33-4, your IFPA Rating shot up to 1655. The next tournament you were included in was the 2013 Waun-a-Pinball where you went 25-29 in the Main Tournament, and 18-2 in the Classics Tournament. This dropped your IFPA Rating down to 1519. It continues to move up/down based on who you beat, and who you lose to. Going 0-100-6 at PAPA B and the algorithm simply hammered you down to where it thinks your skill level is based on those results.

We don't get to choose which results to include and which results to toss out. Perhaps next time don't jump divisions.

Cayle is right.

When you make a decision, be prepared for the consequences, which in this case is nothing more than a rating change. I would not worry about it . I must admit i was concerned with B players not getting WPPR points when i was in that division. Keep trying and working your way up.

(WPPR) Rankings and "rating" are 2 different animals.

Some of the best players in the world and the president of IFPA (also one of the best) are trying to help you understand what is going on. Show a little respect. The system is the same for everyone.

If you want WPPR points or to change your rating, play in more tournaments.

The key word in that quote is probably rankings.

I thought I did poorly in B (placed in bottom 50%), but it actually boosted my IFPA rating - I assume because I was competing against some of the world's best players. I'll go with C next year, but I have no regrets about trying B for my first PAPA.

Unfortunately we can't disregard tournament data based on 'lack of effort', or else we would be getting emails left and right asking for us to not count any poor tournament performance from most players.

The good thing about the IFPA Rating is that it's extremely volatile and adjusts quickly to try and find the most accurate skill rating. Keith Elwin is currently one of only 3 players with an IFPA Rating of >2000, and I can tell you on more than one occasion Keith's IFPA Rating has gone down over 200 points from a random side division of a tournament where Keith played one run and left. Because Keith's typical body of work is to destroy everyone in the field, the algorithm quickly bounces back to a more accurate representation of his skill level.

With only 3 tournaments in your resume, there's simply not enough data for your IFPA Rating to have had a chance to settle, so it's moving around like crazy trying to figure it out. As you get more tournaments under your belt, if you perform to your skill level, it should quickly move to an IFPA Rating that accurately reflects that.

You actually brought up a great point that you perhaps wouldn't have played if you knew your IFPA Ratings could be impacted, and that's exactly the reason why we don't use the IFPA Rating metric for anything important (World Ranking, IFPA World Championship qualifying, IFPA State Championship qualifying, $tern Rewards Program, etc). The WPPR system is a 'positive only' system where playing more only gives you a better chance to improve your rank. Any Glicko style metric involves a risk of losing value in your rating by playing.

Josh

We do only recognize open divisions of play for the World Pinball Player Ranking (as stated in our rules), however we do include restricted divisions at IFPA endorsed tournaments in the IFPA Rating because that data is extremely useful in getting players to their accurate rating.

Most other events don't have dedicated restricted divisions that are completely separate from the open division, but for those that do they can submit all results. Many tournaments use the 'Casual Eligible' type of division where EVERYONE is counted in the open tournament, and then a subset of players are then eligible to compete in a different playoff for cash/prizes. Those results are not counted in the IFPA Rating, as those players will already be counted by their open division performance.

For our purposes, restricted divisions are eligible to be included in the IFPA Ratings for players, but only if that division is part of an IFPA endorsed tournament. So no submitting home matches where you beat your neighbors

We do have a sample scoresheet available for download from the 4-player PinBrawl World Team Pinball Championships tournament (most recently held at PAPA).

How do you see the top 25 ratings? I clicked on almost everyone and couldn't find who is rated #2

If you go to he overall rank tables you can click Rating or Eff% and it will sort by that metric.

Here's the direct link for the top 100 by rating:
