Hi Yannis, I only just saw this comment, apologies for the late reply! Thank you for putting so much interest in this - it's great to see some shared interest. I'm really impressed with your Co-op proposal, it is incredibly well thought-out and I can see the chess influence - it could be something to develop Subbuteo to the next level if people become receptive to it. Also thank you for the upgrades to my calculator, it makes everything much more approachable for others and is a great framework to work with going forward. For managing the K-Value, I agree about utilising it to handle new players in a more effective way: I am not currently doing this simply because of wanting to keep things simplified for others to fully grasp, but would be keen to adjust this according to your suggestion in the future. As you know, such a complex system can be difficult to get people to agree with, so my aim for the 24-25 season is to keep going with the English circuit and seeing how everything develops. Using this on a grander scale is something I'd like to revisit at the end of the season when there is more evidence and recognition around the idea, with your input being greatly appreciated within that. Once again thank you for the support on this, I really like the vision you have with the system and how it can be developed further - this is something I will be coming back to over time.
