5,000 hands at 50NL. What does this show?

Line goes up and to the right at a very high rate of speed

I'm guessing this is online, as 50NL is pretty rare live and basically impossible to track at that level of detail, so I'd post either in an online sub-forum or in the beginner's sub. This is a sub for live. If it is live, please repost in the winrates thread with some more details about the game, number of hours, average session length, etc.
