Beating the bubble and consistently winning more
i play $10 sng's on stars and im looking for some help to more consistantly beat the bubble. I started about 2 months ago and my bankroll is up a little. whilst im happy to be ahead i seem to be stuck and i would like be able to build my bankroll and win more consistently. i recently purchased poker office, which shows 50 $10 sng for a profit of $43 (10 firsts, 4 seconds, 3 thirds), and 15 finishes in 4th or fifth which i think could be improved. is this too many bubble finishes? i try to be much more aggressive on the bubble but it seems to come unstuck a lot.
any insight or tips to profit more would be greatly appreciated. also if any more stats from poker office would help let me know.
