I learned many things about the SFA last season:
The first piece of statistical analysis that's been commissioned by Bob's Statistics is the Free Kick Table. Free kicks are a very emotive topic in football, however it seems that the 'random' nature of qootball displaces that emotion from umpires to the sim. One way to look at this is a free kick differential, which aggregates free kicks over a period of time and shows which teams receive more than others.
My Free Kick Table takes this one step further, and aggregates the impact of free kicks on a game-by-game basis to see who won the free kick count in each game. So pretty much what would happen if you replaced goals and points scored with free kicks received. My hypothesis is that even though there should be minimal variation in the overall aggregate of free kicks over a season, however the variation would be greater in the aggregation of free kick results per game over a season. Or to put it in terms that stats nerds will get a semi over:
H₀: Variation in overall FK aggregate = Variation in FK game result aggregation
H₁: Variation in overall FK aggregate ≠ Variation in FK game result aggregation
Trying to describe it in words is one thing, but an example would seal the deal right?
Thanks Heisenberg!
So to give you all an example of how it works, here's the Free Kick Table for season 29.
Legend:
Win: Number of games where team's free kicks > opposition's free kicks;
Draw: Number of games where team's free kicks = opposition's free kicks;
Loss: Number of games where team's free kicks < opposition's free kicks;
Points: Like a normal ladder - 4 points for a win, 2 points for a draw, 0 points for a loss;
For: Total number of free kicks received;
Against: Total number of free kicks conceded;
Diff: Differential between number of free kicks for and against;
Home: Free kick differential for games played at home;
Away: Free kick differential for games played away;
Win: Free kick differential for games won;
Loss: Free kick differential for games lost;
%: Differential expressed as a percentage;
Ladder Var: Variation between position in Free Kick Table and Official (Points Scored) Table.
My hot analytical takes on this are:
"Yeah but what's under the covers, Bob?" I hear myself thinking you'll ask next. Well, glad we did. Here's the breakdown for each club:
How about them stats! Easy peasy, feelin' queasy.
So there's your baseline. Throughout season 30 I'll keep track on how the Free Kick Table is progressing, and will provide regular updates & analysis. Will the trends of season 29 continue? Or will the sim even things up?
Stay tuned, nerds.
- That it exists;
- That it's a community of many campaigners with many different personalities from all walks of life (and that's just TJASTA);
- That the sim is an evil sentient genius that, underneath its randomness has patterns that it forms;
- That RookieChat is a powerful force for good;
- That a representative team comprised primarily of midfielders caused the downfall of the Roman Empire;
- That producing stats-based threads is the key to winning bullshit awards.

My hot analytical takes on this are:
- Warriors were stone cold robbed, as were the Dragons & Bears to a lesser extent;
- Roys were kissed on the peen;
- Bombers & Gumbies were unable to convert free kick success to regular success;
- Furies were able to take advantage of the free kick support given, as were the Demons;
- Swamprats punched slightly above their weight;
- Royals weren't loved, either by the sim or themselves;
- Whoreks & Wonders were average.
