I use mustard in my egg salads and tuna salads. Mayo too, but only just barely enough of it to 'bind' the salad. In my household I think I use up 2-3 bottles of mustard before I get halfway through the miniature jar of mayonnaise. This chart basically reads like an upside down version of my own condiment preferences (though I do not use soy sauce at all, I use liquid aminos for recipes that call for soy sauce).
