When I think about patience in football, it is actually a very practical thing. If you don't provide it, you end up shooting yourself in the foot anyway.
Obviously the opposite of having patience is losing patience. Even when you have natural patience, you an still lose it and that felt like the Ange path. Why we lost patience is the more interesting angle especially when you get into the "why". There are so many stakeholders in football and they can all lose patience at different rates. Obviously, some clearly don't at all and maintain the belief. With Ange, the reasons the stakeholders lost patience was multi-faceted. It wasn't just about the black and white things like league finishes. It was in the micro-detail that we all lived through every day for 2 seasons. The stuff that I was saying I can't see with Amorin as my focus isn't there.
All you can hope for with fans is that they at least start with best intent on any new manager. I definitely did with Ange. He lost my support through his words and actions.
So I don't think patience is earned in the first 2 seasons as it should be a practical given. I think it might be though as you move beyond that point and really start to head into a long term relationship with a club like we saw with Poch.
