10% ROI is good to start with.
Contrary to what TP suggested, I would tighten up some more. If you can finish less in 6th and 7th (stay patient - blinds still small!) the numbers will distribute more in the top half, which includes first, second, and third.
ALWAYS REMEMBER: the point of a SNG is to make the top three. Once you do that, then you focus on first place.
In General, turbo SNGs are more push/fold poker when the blinds are heavier... that is, exploit your pre-flop edges when your M gets to 10ish. Turbo SNGs are meant to be won pre-flop.
