I am looking for any advice/articles relating to bb/100 from blind levels and for sngs.

Over 120k hands i have a negative stats for BB 50 to 120 and i'm trying to find out what my leaks are.

vpip/pfr/agg all increase for every blind level but my blind stealing is not increasing enough for these blind levels..

I know this isn't a strategy forum but any advice including links to articles or videos for plugging leaks in sngs would be welcome.
