True, at that extreme, it's big, and I probably could state my claim more precisely.
Here's my claim: if you drew a curve of electoral votes per person by percentile, there would be a very small area that was significantly elevated, and the remaining portion would be moderately flat.
Because Wyoming's population is so small, the absolute impact isn't that big. Go up just a few spots to Hawaii and it's more like a 2:1 ratio. Yet still, substantially less than 10% of the population lives in such small states. So there's a very small minority of people who have a proportionally larger impact (but still a small impact in absolute terms).
To be clear, I think that's a bad result. So far as the democratic process can allow it, our votes should have equal weight. But it's somewhat exaggerated how systematic of an effect it has. In the same vein, I've argued that the best defense of the electoral college is that it only errs by giving the wrong result in elections that were already very close. In contrast, the Senate is thoroughly anti-democratic, unsalvagably so.
(Btw: I can't replicate your math. New York had 19,378,102 people in 2010, and 29 votes = 1.49 votes / million. Wyoming had 563,626 and 3 votes = 5.32 votes / million).
