I have a question concerning ROI....
I have been a winning recreative player for about 2 years now, and, although not my main game, Ive played quite some one table SnG's + matrixes.
My main game I suppose is playing multitable sit n go's 18 & 45.
I have good lifetime 20%+ ROI's on these.

Im trying to get things rolling a bit, so Ive started to invest in buying HEM & studying a bit(only when I feel like it tho, its still recreation for me).
When I look at my stats, I notice Im hardly in the + on one tables (Im playing 6,50 turbo's) and have never been a big winner on them via sharkscope.

Since Ive gotten HEM, I have 2% ROI on I believe 150 sample size(not on my own computer atm). I know this is too small, but this combined with my sharkscope stats Ive concluded that there is something going structurally wrong.
Im not on a huge sample size yet, however I cant seem to find my leaks.

I am trying to think of the big differences between one tables and multi's.
Ive always theorized my edge is smaller the less ppl are in.. but is this really so? If 30% of the fieldis fish, this should not matter.

I know to shove wide when blinds are killer etc. etc.

What Im asking here really is, has anyone else made this switch, and what were your common mistakes when you switched?
What are most common differences?

I do notice that I play bubble very agressive, resulting in my finish distribution so far is 1st the most, I believe followed by 4th. 2nd & 3rd are somewhere in the middle. These are not yet telling the whole story I think, because of sample sizes.

One tables are much more ICM orientated since $EV is king, where as the further you are from the money in a MTT the closer cEV will be to correct. Therefore a correct play in a one table can be totally incorrect in a MTT. For example, playing slightly looser early in a MTT can be a winning strategy if you can do it well but is never a winning strategy in a STT

Sample size is too small to draw any conclusions - 1k STTs minimum.

Read the FAQ and post hands as well.

I do play a somewhat LAG style, even on early blinds.
As stated, I dont have access to my stats atm, but will post vpip/PFR once I get home.

TBH I havent even looked if theres something leaking on the lower blind levels, since I never figured this could be the problem.

I only nitted it up at the matrixes, cause there 5th>9th.

BTW sorry if I shouldve posted this in the sticky. If so im sure a mod can move it for me

Therein lies the problem then probably. LAG style will never be a winning style in 1 tables...

I do make good BB/100 with it tho. I realise this isnt a holy stat on SnG's, but I do believe its a good indicator.

Ill post stats when home, cause perhaps your interpretation of LAG differs from mine. back of my head, its something like 20/14.

Actually this is a bit too broad in scope as far as that thread is concerned. You should be reading the FAQ and all of the info in the stickies. Check out hand posts as well, and just read a lot. Check this out too.

As mentioned, tight is right early in SNGs. Spend time working with ICM, and accounting for the payout structure in your estimations of appropriate ranges. If you take the same process with any new game, you'll learn the game and figure out the ropes. New SNG structures are all about adjusting to the payout. Read, read, read. gl.
