Final round for SRP! While we know the top six, the exact lineup for the qualifying finals is still unknown. I’ve written a tool that lets you simulate and visualise the ladder permutations. Click for details (and link to the browser-based tool). open.substack.com/pub/dimitrip...

Just 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.

Off 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.

Dimitri Perrin @dperrin.bsky.social · 27/10/2025
I’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.

Australia 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...

I have updated my simulations to include the two results from the weekend. Great win for the Wallabies, but consistency will be key to get a top-6 seeding. It is still far from certain: open.substack.com/pub/dimitrip...

A win for the ages, but it does not guarantee top 6

Earlier I was writing in an article draft that we haven’t seen a 25+ margin yet, as one of the many reasons why the season is exciting. If you look at previous seasons or other competitions, it’s 13-28% of the games. I was worried that the Chiefs would force a rewrite, but Moana saved my draft!

For anyone wondering, the answer is yes. Three of the five games from Round 3 of #SuperRugbyPacific have opposite outcomes compared to last year (including the only game that had reversed home and away teams).

People have commented on how exciting the first two rounds of Super Rugby Pacific have been, in terms of both the scoring and how tight some games have been. What I also find very interesting is how different the outcomes have been. (1/3)

If you love @rugbykino.bsky.social's great Champions Cup spreadsheet (and why wouldn't you), I am working on transforming it into a Super Rugby version because a) the season is about to start, b) it will be a tight race, and c) the semi-final permutations are annoying to do by hand.

It’s that time of year again. Teaching evaluations are known to be sexist, racist, and xenophobic. They can be mentally harmful (especially for ECRs). Yet our institutions insist on using them. Remember - you do not actually have to read your evaluations. You do not need to volunteer for harm 🫡
