[EDIT: Those interested in this post might find the bracket charts at the bottom of the IFWiki summary page for the tournament useful as a visual reference. The same charts can be found on this site at https://intfiction.org/t/free-if-playoffs-rules-faq-standings/69042/6.]
While playing with data from the IFDB database, I worked out a way to compare two games via their average scores from people who have played both games. This is similar to a virtual FIFP match between them.
It’s not a perfect comparison, because the overlap of FIFP players and IFDB raters is not 100%, but in general it does a decent job of predicting winners. Of the 63 matches held, only 10 (15.9%) had results that were against prediction. (Another 5 were situations where either the computed averages were equal so there could be no prediction or the recorded votes were equal so the actual result was determined by coin toss.)
I was curious about how the tournament might have gone with only IFDB raters participating, and I found some surprising things:
In Division 1:
-
Dr Ludwig and the Devil vs. Midnight. Swordfight. in Round 1 was predicted for Ludwig by a slim margin on score, and with a bigger margin based on difference in ratings at the individual level. In reality, Midnight won.
-
Had Ludwig won in round 1, it would be predicted to lose narrowly against The Wizard Sniffer in round 2.
-
There was no prediction possible between Birdland and Of Their Shadows Deep in round 1 due to tied averages.
-
Had Birdland won in round 1, it would be predicted to narrowly win against And Then You Come to a House… in round 2.
-
Despite its real world loss, Zozzled was predicted to win against And Then You Come to a House… in round 1 by a slim margin on both average score and ratings preference.
-
Had Zozzled won against And Then You Come to a House… in round 1, then in round 2 it would be predicted to narrowly win against Of Their Shadows Deep but narrowly lose against Birdland.
-
Neither Zozzled nor Birdland would be predicted to win against The Wizard Sniffer in round 3; predictions show strong margins in both cases.
-
Interestingly, the real world result of the round 3 match of Superluminal Vagrant Twin vs. The Impossible Bottle goes against predictions. The prediction would be for a narrow win by Bottle.
-
Had The Impossible Bottle won its round 3 match, it would be predicted to lose against The Wizard Sniffer in the round 4 division championship, sending Sniffer to the semi-finals.
In Division 2:
-
There was no prediction possible between Chlorophyll and Worldsmith in round 1 due to tied averages.
-
Had Chlorophyll won against Worldsmith, there would also be no prediction for its round 2 match against According to Cain due to tied averages.
-
In round 2, The Gostak was predicted to beat Coloratura by a slim margin – in the real world, Coloratura won.
-
Against hypothetical round 3 opponents, Coloratura would be predicted to win narrowly versus either Chlorophyll or According to Cain.
-
Had The Gostak beat Coloratura in round 2, it would be predicted to prevail against either Worldsmith or According to Cain in round 3, but to narrowly lose against Chlorophyll.
-
Against other possible round 4 challengers, Counterfeit Monkey would be predicted to win versus The Gostak, Chlorophyll, or According to Cain, with Cain hypothetically presenting a surprisingly strong challenge.
In the semi-finals (round 5):
- Had The Wizard Sniffer been Division 1 champion, the prediction would be for Counterfeit Monkey to prevail by a large margin.
Based on these projections, it seems that Counterfeit Monkey was fated to make it to the tournament championship round.
I’ll save Divisions 3 and 4 for another day.
