If your stack were ridiculously large it would be unlikely that a rebuy would be +EV unless the payout structure were very unusual (such as a HUGE overlay created by something like added money)

It's also unlikely that rebuying would show a profit at the beginning of most events. Having 20k at the beginning of the main event of the WSOP would be better than having 10 but NOT 2x better unless you hapened to find yourself at a table composed of morons where you were the small stack. The opportunity to double/triple through one (or more) of these simeons might make a rebuy/addon worth it - though possibly not AS valuable as it might seem on the surface.

Anytime you rebuy you are in effect saying you'd be willing (or happy/thrilled) to enter the tournament from scratch at the point of the rebuy.

Taken to its extreme, this is akin to saying that you'd prefer to [re]buy into said event even if another event with an identical buyin/payout structure were about to begin 10 feet away.

- These days, one almost always is about to begin [sic] 10 feet away; this should be taken into account when the rebuy pimp comes looking for you.
