How Far does the ROI Fall as Levels go UP

Is This ITM and ROI sustainable at the micro STT Level
I've finally finished about 100 STTs on Ultimate bet (approx 20k hands), playing at the micro levels 0.50+0.05 and 1.00+0.10. I was able to plug some pretty big leaks in my game and finish ITM about 45% (19-1sts, 16-2nd, 10-3rd) of the time with a ROI of about 47%. Now that the BR has grown I am slowly moving up and playing the micro levels 1.00+0.10 and 2.00+0.20, and was wondering what kind of drop off I should expect as I slowly move up levels.
I believe that the Peter Principle applies here, (everyone rises to their level of incompetence) and want to stop moving up levels when my ROI falls to between 10-20%. Also do you consider the 20K hands enough to be statistically significant.
BTW-Thanks Card Chat, Freeroll money started the micro BR.

the higher the level of ply the lower your roi% is is cause it is harder to win tournaments.

100 micro STT is statisticlly significant although at the $20+ level you need closer to 1000+ tourneys to be able to draw any comprehensive conclusions.

Well, if you want an idea, here what I experienced so far while moving up in stakes. And as mentioned before, the variance does go up significantly when you move up in stakes, and as you move from normal to turbos. I'm not quite sure how significant my ROI at the $22 and $24 stakes are.

Stake (nr of STTs) Profit ITM ROI
$ 0.05 (16) $ 0.40 56.3 50.00%
$ 0.11 (21) $ 1.69 52.4 73.16%
$ 0.27 (34) $ 4.07 44.1 44.34%
$ 0.55 (25) $ 3.25 40.0 23.64%
$ 1.10 (56) $ 15.40 39.3 25.00%
$ 2.75 (116) $ 41.00 37.1 12.85%
$ 5.50 (238) $ 273.50 39.1 20.89%
$ 6.50 (91) $ 40.30 37.4 6.81%
$ 11.00 (74) $ 68.00 37.8 8.35%
$ 22.00 (72) $ 306.00 36.1 19.32%
$ 24.00 (177) $ 424.80 40.1 10.00%
$ 33.00 (9) $ -135.00 22.2 -45.45%
$ 36.00 (10) $ -360.00 0.0 -100.00%

Thats a dynamite ROI...I'd say 20K hands is a pretty good number!

you're ready to move up IMO, but just remember as u go, there are hundreds of others on very similar quests that u will come up against and the silly fishes will inevitably drop off the scene and the $$ will be that much harder to make.

simple reminder...in general

MTT - less ROI
STT - more ROI

over the long haul
