I know it is 2017, but that is a very long time in the gaming/mech keyboard market. I remember just about 10 years ago when mech keyboards were a niche for weirdos and a few others that swore by their Model M's - you now can buy these in Walmart. The point about discrepancy is well taken* but I think the bigger point is on the rtings list the number of offerings that are an order of magnitude lower latency - such that the methodology used in your link is not even viable.
