"I accumulated 30m play chips - so I think I learnt a bit, and play a tight patient game."
-Means nothing, sorry
"Is it possible to come out ahead at this level or should I move up to say $5/10 SNG?"
-No, every single player at your level is losing $$ /sarcasm. If you can't beat $1, no point moving up to bleed more, if you're getting your money in good, nothing more you can do, good luck and hope variance turns round for you
