I didn't usually open them in batches, but I had 2 final tables as chip leader and I was like "this is it, I'm gonna fucking win one, i'm tired of this shit". The reason for my lack of volume (if 300+ in a day can be called lack of volume) is because I didn't sleep at all the previous night, so I zombie-moded it all day. And rest assured I was pushing way looser than chip EV.
I didn't know there was a thread where you can see the daily challenges before they begin.
