Aaron’s Notes

What I’ve been working on, building and learning from FusionSim and everything in between.

Hey there,

I’ve rebranded this newsletter from The Matchday Digest to Aaron’s Notes. Same content, just a more personal touch

Okay, let's get into it.

Sims Until Sandbox is now open for anyone to use and try! I still think there is more I can add to this tool, so please reach out to me in the Discord or on any other channels if you’d like to see any different features or settings added to it.

Additionally, Sims Until retro got a slight UI update and improvement, which is seen in the new animated window for the tool button.

The Champions League Model has been reworked to better incorporate a team’s legacy in the competition and start-of-season form, which, when backtesting, is better when tested on previous years.

This should also bring greater accuracy to the European Coefficients data model, which is all about which nations are most likely to get the bonus Champions League places come the end of the season.

Last thing from me is to say thank you, as always, for all the support on FusionSim, and I am currently thinking about future projects to work on and get stuck into outside of sports data, so if you have any ideas, reach out!

(Don’t worry, FusionSim is not going anywhere!)

Have a great weekend,

- Aaron
