Preprints are read, shared, and cited, yet still dismissed as incomplete until blessed by a publisher. I argue that the true measure of scholarship lies in open exchange, not in the industry’s gatekeeping of what counts as published. 612046

Reposted by MaxMax @oostermax.bsky.social · 19/07/2026Penalty taking and stopping skill for Spain and Argentina. Both teams have excellent penalty stoppers. Argentina got a slight edge in a shootout per my model. Expect Spain to bring in Borja Iglesias for penalties as he has one of the best shot maps around. #WC #WorldCup #ARGESP #WorldCupFinal 042

Max @oostermax.bsky.social · 15/07/2026Penalty skills for England - Argentina. England have some of the best takers in Harry Kane and Ivan Toney, but Argentina has an edge in the shootout if England play Pickford instead of Henderson. #WorldCup #WC2026 #ARGENG #WorldCup2026 #FIFAWorldCup 110

Max @oostermax.bsky.social · 15/07/2026based on my simulations you should prefer the best GK by quite some margin! 110
Max @oostermax.bsky.social · 15/07/2026In a penalty shoot out, which team would you pick to win? 1: best 10 pk takers in the world (eg Kane), but the worst pk GK (Begovic) 2: worst 10 pk takers (eg Chricarito) but best pk GK (eg Diego Alves). Simulation informed answer to follow! #WorldCup #WorldCup2026 100
Max @oostermax.bsky.social · 15/07/2026related to the penalties: I have looked into penalties extensively and written up two blog post on it (see maxoosterwegel.com) and have made Bayesian skill estimates available for 300k players (penaltystats.maxoosterwegel.com incl so simulator!) and yes Messi is actually below average probably 210

Max @oostermax.bsky.social · 11/07/2026My model even suggest that England's chances of winning a shootout vs. Norway jump by 10 percentage points if Henderson is in goal instead of Pickford. #WorldCup #WC2026 #NORENG #WorldCup2026 #FIFAWorldCup 100
Max @oostermax.bsky.social · 11/07/2026Tuchel would never do it because England has won 3 shootouts with Pickford and I imagine the media backlash would be huge if they lose (and pks are still a game of chance), but Henderson has been the better penalty stopper in his career by far. #WorldCup #WC2026 #NORENG #WorldCup2026 #FIFAWorldCup 121
Max @oostermax.bsky.social · 10/07/2026he likely is their best penalty stopper by far so i can see the logic beyond the coach just sticking with what he knows 010
Max @oostermax.bsky.social · 10/07/2026Note that I did not say anything on if this would help Belgium get to a shootout in the first place 000
Max @oostermax.bsky.social · 10/07/2026Penalty taking skills quite similar between Belgium and Spain #WorldCup #WC2026 #ESPBEL #FIFAWorldCup 010
Max @oostermax.bsky.social · 10/07/2026Courtois off injured for Lammens. If the match gets to pks, this may in fact increase Belgium's chances as my model gives a 63% chance that Lammens is the better pk stopper. They need every advantage they can get with Unai Simon being one of the best penalty stoppers #WorldCup #WC2026 #ESPBEL 200
Reposted by MaxMax @oostermax.bsky.social · 09/07/2026France - Morocco penalty taking and stopping skills. Two of the very best penalty stoppers with Maignan and Bounou. Both teams consist of very average penalty takers on the other hand. If they get to a shootout, we may see multiple saves. #WorldCup #WC2026 #FIFAWorldCup #FRAMAR 122

Max @oostermax.bsky.social · 09/07/2026Bounou and Maignan penalties faced maps. Both among the very best at both reading the taker's intention, and saving the penalty. #WorldCup #WC2026 #FIFAWorldCup #FRAMAR 110

Max @oostermax.bsky.social · 07/07/2026some of the best pk takers in the world do something like a stutter (eg Kruse, Bruno Fernandes, Lewandowski) players with stutters consistently show up as best deceivers iirc (see my blog). i would say it’s a high variance skill: some do it exceptionally well, others quite horribly bad 110
Max @oostermax.bsky.social · 07/07/2026true but hard to model that of course! though I think it’s mainly that you invite critique with a substitute. no one bar some twitter rando like me will be disappointed if you don’t make the substitution 000
Reposted by MaxMax @oostermax.bsky.social · 07/07/2026and here are the other estimated skills for both teams. Camilo Vargas is really excellent at stopping penalties! Columbia their penalty takers seem to be (sub)par. #WorldCup #WC2026 #FIFAWorldCup #SUICOL 001
Max @oostermax.bsky.social · 07/07/2026let’s hope so! what do you think about my Swiss substitution call? 100
Max @oostermax.bsky.social · 07/07/2026their penalty takers are indeed not good but their goalkeeper is very good! bsky.app/profile/oost... 100
Max @oostermax.bsky.social · 07/07/2026no goalkeeper substitution by the Swiss. this could cost them.. (or not because football) 000
Max @oostermax.bsky.social · 07/07/2026pretty much expected with the amount of money there is on the line no? also, as a fellow epidemiologist you may be interested in my statistical modeling during this WC, e.g. bsky.app/profile/oost... 020
Max @oostermax.bsky.social · 07/07/2026if Switzerland vs Columbia gets to a penalty shootout, they should bring on Keller for Kobel to increase their shootout chances by 8 percentage points (per my Monte Carlo simulation based on estimated skill levels)! #WorldCup #WC2026 #FIFAWorldCup #SUICOL 000

Max @oostermax.bsky.social · 07/07/2026If we get to a shootout, Switzerland would do well to sub Keller on for Kobel. My model estimates a 77% chance that Marvin Keller is the better penalty stopper. And according to a new model of mine, this could improve their chances from 39% (with Kobel) to 47% (with Keller) in the shootout! #SUICOL 110
Max @oostermax.bsky.social · 07/07/2026he spreads well which makes him harder to read, and he usually leathers it which explains why he outperforms the expected goals (no data on ball speed). the leathering may also explain your nerves? 010
