Oh... Well, that explains that. Doesn't look like it's available offline, though. Shame, but it makes sense considering how dangerous higher ratings can be.
Because I'm a sucker for useless bits of information, I did a little search and found that
your putapario peppers are actually rarely harvested and VERY rarely sold commercially. They're more of a local specialty food than just another spice, which makes giving them a Scoville rating damn near impossible.
If you want to personally try to rate it, Scoville numbers correlate to how many parts water are needed to dilute the pepper's flavor enough to eliminate the burning sensation. So try this:
1. Squeeze one of those aji putapario peppers until a single drop of juice comes out.
1 drop = 1/96th of a teaspoon, and 1 teaspoon = 1/203rd of a liter. So, if you add a drop of the pepper to one liter of water, drink some of the water, and still can taste heat, the pepper has a rating of at least 1(19[203]) = ~20,000. From there, basic math and more/less water should get you an answer.
Bear in mind that this is a really nig-rigged method and the end result will be vague at best. But it'll at least tell you which neighborhood of peppers yours are closest to.
