I'm almost halfway through the challenge.
To make 100k hands takes me time because I also play at the regular table. Unfortunately, my shot in NL25 regular didn't go very well so I spent quite a bit of time in NL10 regular to make up for my losses.

Between 20k and 30k hands, I had a big downswing. It appends just after my downswing at 25NL after which I worked on my game by studying GTO...
My problem is that I started to become a big calling station, I started to hero call underbluff lines in order to be balanced. Got check raise on the turn? No problem, I can call, they bluff sometimes and I need to defend x% of my range, on top of that, I block villain's value hands... Got 3 barrel all in by out of position player? No problem, they bluff enought, I can call... Villain represents AK making a straight when he goes all in river? I don't believe him, he didn't 3bet...
My other problem is that I started bluffing lines that are overcall. Villain overfold flop, villain overfold turn, my database told me that the field overcall river, but I don't care, I am playing GTO, I have to find bluffs on the river... Villain comes to the river with only nutted hands, but maybe he can still find a fold? I have to be balanced if I want to be a crusher...
Around the 30k hand, I realized that I had to play my usual game again, start exploiting the field again, continue to improve and regain confidence at the tables and a more controlled aggression.
