Dimitri Perrin @dperrin.bsky.social · 18/09/2026Super Rugby has been doing synchronised team announcements on the Wednesday afternoon, and it is working well. 000
Dimitri Perrin @dperrin.bsky.social · 24/05/2026Final round for SRP! While we know the top six, the exact lineup for the qualifying finals is still unknown.

Dimitri Perrin @dperrin.bsky.social · 31/01/2026New season about to start, and just like the players tuning up in today’s pre-season game, we are also preparing some exciting things on the data front. If you want to be part of it, get in touch! We have a targeted call for PhD Scholarships for domestic students: www.qut.edu.au/study/fees-a... 000
Dimitri Perrin @dperrin.bsky.social · 08/12/2025I’ll miss the show (like a lot of other people), but I’ll follow what comes next. Now the question you posted earlier takes a different meaning! 010
Dimitri Perrin @dperrin.bsky.social · 03/12/2025For today I’ve kept things simple: the higher-ranked team wins. We have two years to be build more sophisticated models. 😅 001
Dimitri Perrin @dperrin.bsky.social · 03/12/2025Thanks. It was a lunch break well spent earlier today. 000
Dimitri Perrin @dperrin.bsky.social · 03/12/2025B.B. King & Ray Charles must have been great! I've heard B.B King live, but not seen him (I was outside the open-air venue when he played at the Jazz à Juan Festival). 110

Dimitri Perrin @dperrin.bsky.social · 03/12/2025Samoa also has the easiest draw of all band-4 teams. Of course, it will only matter if they improve, but they have a great opportunity, given how much worse it could have been. 112
Dimitri Perrin @dperrin.bsky.social · 03/12/2025For each set of four best third-ranked teams, there is a unique permutation. 110

Dimitri Perrin @dperrin.bsky.social · 26/11/2025Australian teams need more games. The new Super Rugby Aus competition provides some opportunities. If cost was no object, I’d like to see it longer (as well as going full home-and-away for SRP). 140
Dimitri Perrin @dperrin.bsky.social · 26/11/2025Super Rugby Pacific is only 16 rounds of regular season, with two byes per team, so 17 games if you make the final. That’s 31 total with the internationals. 110
Dimitri Perrin @dperrin.bsky.social · 09/11/2025Just arrived in Sydney for the ADSN conference, hosted by @sydneyprecisionds.bsky.social. If you’re here too, let’s catch up during the breaks. Our Centre is represented on all 3 days. Today, you’ll hear from our members during the “fast-forward” presentations and the poster session. 020
Dimitri Perrin @dperrin.bsky.social · 01/11/2025Almost 20 years across the two countries. It leaves a mark. 😅 010
Dimitri Perrin @dperrin.bsky.social · 01/11/2025Just arrived in London. So far, two English jerseys and five South African ones. Now to find a good place to watch the games. Any recommendations near Wimbledon? Ideally somewhere that would have decent numbers of Irish and/or Australian, so that I’m not alone cheering for these two teams. 110
Dimitri Perrin @dperrin.bsky.social · 28/10/2025The flight from Brisbane to Perth was fine, but it was the easy part. 000
Dimitri Perrin @dperrin.bsky.social · 28/10/2025So far today, I have spent longer in airports than in the air, but it is all about to change with a massive 18-hour flight from Perth to London. Wish me luck! 😴 210

Dimitri Perrin @dperrin.bsky.social · 27/10/2025Off to the UK, where the weather probably won’t be great, so Brisbane has decided to help my transition (from yesterday’s 38.5°C) by making this morning wet and miserable. Sorry everyone, it might be my fault. 010
Dimitri Perrin @dperrin.bsky.social · 27/10/2025Yeah, I still need coffee, but at least I’m not crazy. Have a good flight. 010
Dimitri Perrin @dperrin.bsky.social · 27/10/2025I’m working on an update of my rankings simulator, to look more closely at the path to a top-6 for the Wallabies. Now that they have “only” four games left, it is more manageable to look at specific combinations of results. I should be able to post that later today. 010
Dimitri Perrin @dperrin.bsky.social · 27/10/2025I think I’ve seen a @bmcsport.bsky.social in the wild. Or an excellent lookalike. Or I need coffee. 😅 100
Dimitri Perrin @dperrin.bsky.social · 20/10/2025When there’s something to be won (such as next year’s Six Nations), you could argue it makes sense (not least financially), but for this November it seems very different. 110

Dimitri Perrin @dperrin.bsky.social · 29/09/2025It depends how we define fairness. Does a fair draw give teams an equal chance of reaching the round of 16 (irrespective of their strength), or does it give them a probability that is as close as possible to their strength? And do we maximise average fairness, or minimise the largest unfairness? 000
Dimitri Perrin @dperrin.bsky.social · 29/09/2025Yes, I’ve noticed that it is what you have done, but I wasn’t sure what made it fair. It makes being ranked 6th the best possible ranking (assuming that the rankings actually reflect team strength). 000
Dimitri Perrin @dperrin.bsky.social · 29/09/2025It depends what you mean by fair. Is it about giving relatively weaker teams a leg up, to increase competition, or is it about rewarding higher ranked teams? 100
Dimitri Perrin @dperrin.bsky.social · 14/09/2025You’re very welcome. Pre-ordered and all set to dive into it once it drops. 000
Dimitri Perrin @dperrin.bsky.social · 14/09/2025Australia dropped to 7th, but looking at a single week does not give you the whole picture. You need to look at all possible results, so it is time to update the rankings simulations. Everything is still to play for, not just for the TRC. open.substack.com/pub/dimitrip...open.substack.comBack to square one?If everyone is special, no one is. 010
Dimitri Perrin @dperrin.bsky.social · 12/09/2025This should be a good read. I’m looking forward to it. 110
Dimitri Perrin @dperrin.bsky.social · 17/08/2025It might have been Jonathan Drennan’s SMH article. It was pretty good, but missing the impact of the sequence of results as well as the results from the other teams. That’s where the simulation tool becomes handy. It captures all games, rather than just the Wallabies. 010
