Passing out on EV+ situations?

I just started thinking about this, but I cant quite reach a conclusion.

If SNGPT says it's a clear push, (0.7%+) concidering your table-image as well, does that always justify making the push?

I'm guessing the answer I'm gonna get is no, so, in what situations should I not make the EV+ push waiting for an even more EV+ situation? I'm thinking ITM play should maybe be played more by feel than by ICM. Waiting your opponents out and catching them off guard instead of pushing slight EV+ situations, manipulating them into thinking you dont push any hand etc etc.

So the question: when is it most likely correct to pass out on EV+ situations? ITM? At the bubble with a lowstack out there (how low?)? As a highstack nearing the bubble, almost guaranteeing yourself ITM?
