Yeah, I'll try to adopt the strategy this season instead of just yolo-ing into things. Imo, the biggest issue I would have is having the discipline to stick to the strategy in both good and bad betting days. I believe if I can do that, it might work out. I'm saying this from experience because last season I started something like this with a spreadsheet I updated with every new betting and the outcome. It was easy to follow when I was winning but when shit hit the fan, my discipline went out the window and everything went downhill after that. There was no recovery.
In this case, you need to decide whether you want to place bets as effectively as possible to maximize your return, but at the same time put in a lot of effort. Or you don't want to put in a lot of effort, but you understand that the long-term results of your bets will be worse. In the first case, you act in a disciplined manner, keep a table as you have already done, and do not neglect to keep statistics, no matter what happens. In the second case, you probably do what most betting enthusiasts do: you simply place bets whenever you feel like it, but at the same time you do not particularly count on the effectiveness of your bets. In principle, both styles have their place. There are some unique individuals who don't bother with any of this, but their bets still give them good results, although this may be partly due to luck.
