[There's no need to use a page cap. The left menu shows the number of sales. You can just search for monero vendors and work out the percentage.
Stimulants:
Total sales: 23347
Monero sales: 425
= 1.82%
That's just wrong. [Firstly, these are not sales. These are listings. Secondly,] you're comparing the result of a search by one process with some unknown reported number. There's no evidence that this number is comparable, or even accurate, since it can't be mapped to actual listing. You're comparing apples and oranges. The page cap is imposed by the site, not by me. To make a valid sampling you have to sample both populations the same way. You can slice it to get under the cap (as I did with the use of trust level limits). I don't know of any other way to sample both populations comparably.
Stimulants, level 9-10, gives 8 XMR listings and 62 BTC listings, or 13% XMR support.
Stimulants, level 7-8, gives 47 XMR listings and 103 BTC listings, or 46% XMR support.
That is a valid comparison. Your numbers are just a units error, statistically incoherent.
The more interesting numbers would be the sales volumes. Because if sales volume is increasing, we're golden, and it doen't matter if 13% (the lowest number in evidence) or 46% (the highest number in evidence) of the vendors are supporting XMR.'
Yep, pure FUD, I also checked some listing on my own since those numbers seem very low.
