That amount could come ALL from one player or 1/2 from one player and 1/2 from another player in a multiway pot or whatever summed value profit is greater than or equal to that #. It doesn't matter where the money comes from so long as you make at least that.

Since you're talking "rule of thumb" then 15x plus is better, especially since we're usually weighing this preflop. Odds of improving to a set on the flop are 1 in 8 or 7:1. It's rare we're multi-way past the flop, rarer still that we get villain's full stack so we hope to get half or more, and even rarer that we're getting paid by more than one opp.
