You're right that we only have a handful of countries operating at this scale (~150M+ populations) so it's not exactly "data" in the common tech-sense of that word. I want to get back to my original point: it's not "astoundingly clear" that the US should have a single-payer system (not your words, I know). My own thoughts are that this is mostly a scale problem as well as an inability to properly assess the performance of other systems (e.g. I would call both Canada and UK healthcare broken, but others see those as successful). I agree that the US system seems broken from both an "Outcomes vs Cost" and a "Cost over Time" perspective. I just disagree that nationalizing healthcare, either through a single-payer system or the current Obamacare system is the answer.
