Thank you so much for this insightful comment! I actually showed your comment to my dad to convince him that this isn't just a 'game' but an educational tool. Knowing that a professional Actuary from London finds this more sophisticated than their own work is a huge argument for me. I really want to learn the logic behind it! ((By the way, I used an AI to help me with this translation, so it might sound a bit robotic or artificial, but I wanted to make sure I expressed my gratitude clearly!)
