Sambal Asli is something like 2500 Scoville. That is an extremely mild level of spiciness. If you thought your face was burning off with that your spice tolerance is incredibly low.
I think the lesson there is that subjective / comparative judgments are, well, always and irremediably subjective. It's never possible to impose an alternative frame of reference and get to a "true" answer. That's frustrating for those of us who prefer to live in the objective realm - but it's maybe comforting to recognize that these matters are objectively subjective!
