Even though the columns for R1000/3000 are not regularly updated, they do provide some values when they are updated. The UR reward at R3000 matters for new players or lazy players like me... I don't have any actual demographical data but I believe a large portion of people who read this wiki are not rankers like you guys are.

Granted the actual numbers might not be as "close" to the true ranks as we would like, but that's why you have a tooltip telling you what is the actual rank for that point, and you make a guesstimate from there. Any number is better than no numbers in my opinion.
