Keep in mind NIN in 2022 doesn't have the leading act draw they had in 2000, and that isn't the same as say 1990.

We need metrics that include their popularity/ticket sales, etc.

I paid $100 a ticket in 1985 for a stadium sellout band at the time. Ten years before my older siblings paid $40 for the same band.

I mean, there's a drastic difference in cultural relevance over those 20 years. 2000 was at the tail end of their peak. Supply/demand would certainly affect the equation.
