Yeah the CO situation is a mystery to me... I did some filtering in HEM today trying to see what might be the issue but I didn't come up with much. Any ideas about what I should be looking for that might be a cause of that?

And yeah penney I know it does look like I went on a heater at the end there... I definitely did to some degree, and what you say definitely makes sense about the signs that it's a good idea to move up, thank you. But yeah the last 5k hands I played on that second graph definitely felt like I was winning more consistently and playing more solid... granted it's small sample size but I'm happy to move back down if it turns out I need some more time.
