Product rankings run straight off product points, with no decay over time.
A product launched today is ordered by its current points, updating close to the moment a new interaction lands.
A product gets exactly one daily record, snapshotting its points on the day it launched, right after that day closes, at 00:05 Vietnam time.
The weekly board ranks products launched that week by the points snapshotted on each one's launch day, calculated Monday morning for the week that just ended.
The monthly board ranks products launched that month by the points snapshotted on each one's launch day, calculated on the 1st for the month that just ended.
The yearly board ranks products launched that year by the points snapshotted on each one's launch day, calculated on January 1st for the year that just ended.
The all-time board orders products by their current total points, recalculated daily.
An upvote adds product points equal to the voter's weight. That amount is then multiplied by whatever boost perk the product's primary maker holds at their level, and rounded to a whole number. A vote from a higher level, a verified account, or someone with several badges always adds more points to the product.
Product points stay once earned. Rankings never subtract points for age, so an older product does not drop just because a newer one earned points faster in the same period.
Maker trust is calculated with its own formula, based on a percentile across all makers.
