I know there are a few items (Velvet Cloth singles, Yagudo drinks) that have sell rates that are far, far above the "Very Fast" category. For this class of items (probably about 100 I'd guess, offhand) I think there should be a separate category or handling for. It would be nice to get the real sell rate as well, somehow, perhaps by having the bots that scan the ah check the history for these items more frequently than they usually do. I'm guessing the yag drinks sell around 200+ per day, about 10x what the site currently sees it at.
I understand how the scanning works, and that if the history has been effectively flushed, sales get missed. But the items that have this issue are widely known, perhaps they could be visited more often to lessen the chance of skips and get more accurate data?
