Heads up ROI

What's a good ROI for heads up SNGs for the following buy-ins?

5+.5
11
22
33
55

Anyone played a thousand or more of these heads up?

jesus dude, couldn't your questions about basic statistics for the hu sngs have all fit in one thread? what next some questions about the difference in quality of play between the 5s and the 10s?

try using the search function.

Can you please provide any links, Citanul?

Come to think about it I need to know the differences in skill levels between buy-in amounts too. But I'm most interested in links that talk about SD, BR requirements, ROI, and minimum sample sizes.

I could be wrong about this, but I don't think you'll find the answers by searching this forum and I don't think that anyone who will read this can help.
