Hey Sir,
Could you perhaps include some sort of timeline in this post?
Also, your 2k BR sounds small for the 5/10 limit. If you're worried bout variance, it would make sense to have too large a BR, and not too small.
You read 'gambling theory and other topics'? I believe much of it is about variance (haven't received it yet, still in mail

).
Poker Essays 2 has some interesting chapters on sessions, odds, and variance. Also has lots of other gems in there. Great read.
Anywho, you're playing 5/10 which to me is very high. I feel almost dirty for giving you advice

.
Cheers,
Gutzz
