Actually I am studying for ~2 hours daily my sngs using SNG wizard, and it says that I am doing (most of the time, like 89%) the correct decision (push/fold) and somehow i just keep losing in these hypers.
I am using some charts that are provided at pokerstrategy about push/fold, here my "cheat page":

I know some ranges are tight but at the same time i think it is ok, because people at these levels ($1.5 6max hyper sng) shove ATC pre in the first levels and just end up sucking out. Just open the ps client and open (observe) any 6max sng that is starting and ssee what people shove, they shove practicaly Qx, Kx, Ax, any pair, J8+ and any two suited cards.
