Using 80 stamina & 1 raid point:

?-3 (twice) gives you 17 + 50 + 17 = 84 (clear twice & participate once)
If we spend another raid point to participate in the 2nd boss then you can add another 50 on it which brings it to 134.

Think of it this way instead:
3 raid points on a high level boss will give you approximately 75 * 3 = 225 silver
3 raid points on a low level boss will give you approximately 45 * 3 = 135 silver
Hence why I feel that you should always use your raid points on ?-4 raid bosses.

Stamina doesn't really matter in the sense that there are always more bosses available than you can afford to participate in, so using your stamina on other stuff is what I would recommend. Of course, if there are no raid bosses available, that's when stamina should be spent on spawning your own boss. But even then I'd recommend going for the ?-4 because doing ?-3 twice costs 2 raid points which could be spent on other people's high level bosses.
