should i move up stakes

I would say there's not much difference skill-wise between 5nl and 10nl so if you have the bankroll, then sure

Yes, move up. Do it now!!

Move up man. Only ******s play 5nl

You're up 5 ev stacks at 5NL after less than 12k hands. Move up if you want to and can afford it, but zero conclusions can be made based on this sample/graph.
