Not quite, as far as I can tell. It provides the average, and the number of voters, so it’s possible to calculate the total, though I don’t see a way for the poster to get the raw vote data (maybe an admin can; I’m no expert on Discourse). But I actually don’t care; despite some poorly-defined metrics that conclude that score voting is better for overall satisfaction, it’s really not the correct model for a product with no competition. Approval voting is obviously superior in this case, since there really are only two options: “Do I buy it, or do I not buy it?”
As far as I’m concerned, it’s only worth looking at preferences if there’s a tie on an approval vote first.
