If, OTOH, one wanted a hard boiled egg, and there was 
already one in the fridge, and assuming that normal people can't 
tell the difference between just cooked and one day old, and 
further that there is no significant possibility that a second egg 
will be needed that day of Yom Tov- I would assume that it such a 
case it would be assur.

I believe that one may almost always cook something on YT and rely on the possibility (it need not be a likelihood) that unexpected guests will come and the cooked food will be used to serve them (Shema ikleu orchim). Indeed, in the last minutes of YT, where there is virtually no possibility to use the food for such theoretical guests, it is forbidden to cook food one does not need at all for YT. I don't know exactly how close to the end of YT one has to be for this prohibition to apply, but my impression is that we're talking about a matter of a few minutes.
