Okay, these last games skewed my 9 inning game results because I used the next 100 biggest files in the box scores folder, so ignore the 9 inning games.
- 8.5 Inning
- 5.329 Average
- 2.893 STDEV
- 152 games
- 9 Inning
- 7.137 Average
- 6.198 STDEV
- 227 Games
- 10 Inning
- 14.818 Average
- 2.8 STDEV
- 33 games
- X>11 Inning
- 17.5 Average
- 4.778 STDEV
- 88 total games
- 12.5 Inning/ game average
Based on these results, I see a 8.918 sub/game average, but again these are skewed since normally you won't see this high a proportion of extra inning games.
The number that scares me here is 14 average in 10 inning games. It has a low STDEV, but only half are from a random set. If thats accurate, it equates to approximately an extra 4 substitutions per team as soon as extra innings take effect.
Interestingly, there was one incredibly weird game that went 14 innings with 9 total subs. However, all 9 of the subs were on the visiting team. The home team made 2 pitching changes in 14 innings, and those were the only moves they made. Hrmm.....
