I built a @streamlit app to demonstrate the folly of drawing broad-brush conclusions from single match xG aggregations (the kinds that tend to get lots of traffic on social media):

@justintickner Thanks mate

Bottom right a massive gee up surely @justintickner haha

@AndyHowe_statto @aleaguemen Has there been a material increase in injury time minutes this season, noting this appears to be a thing in many leagues globally since the 2022 World Cup? And if so, does the record still look close on a per minute/hour basis as opposed to per game?

[Justin Lyons @lyonjust]

@Hirald0 @VinceRugari Tilio is the former holder of the record as it's now Gauchi - "former" isn't being used in the former/latter sense between Robertson and Tilio. 🌝

@TheRealALM Did it from 7th with the Jets in 13/14 so just playing on legendary mode this year I guess.

@M1D3V Because his goals per 90 tonight is 22.5. 😏

@safreireleo @SimonGleave Thanks Leo, it's nothing too crazy, just a Monte Carlo simulation of each shot attempted assuming chances are independent and identically distributed. Which is a bold assumption in some cases e.g. missed pen but score rebound.

You can see the code here:

@justintickner No problem thanks mate

@PawarBI 1. Calculate moving averages in DAX to smooth trend lines.
2. Facet into small multiples.
3. Filter out categories that aren't important, or aggregate into fewer categories.
4. Apply subtle light grey colour to all but 2-3 key lines.
5. y logscale to compare growth, not absolute.

@AnalystShlok Very nice! Do you mind sharing the data source?

@xGPhilosophy This is insane.

@aleaguemen @WgtnPhoenixFC Ridiculously painful to watch in cropped aspect ratio.

@visualisingdata Got five codes to giveaway here if anyone wants.

Growing chatter about generative analytics seems to mostly be about how well text-to-SQL/chart/report will work. Idk the answer but I'm pretty sure it's the wrong question. If today's charts/reports/queries generally do not create significant value, why would more of them?

@ALeague_xG Perth stitched up by the xG gods again. Did enough to win this game 8 times out of 10. Dropped points last week when they get the chocolates 9/10 times.

[Justin Lyons @lyonjust]

@ALeague_xG Jets scored from a 0.04 xG and a 0.10 xG opportunity haha. Perth win that 9 times out of ten. #PERvNEW

@infobeautiful Why is this a tree map? Am I missing the hierarchy?

[Justin Lyons @lyonjust]

@james_r_mcgrath Hijacking this to say I have three codes to hand out to #sokkahtwitter if anyone wants please hmu.
