Have you noticed how the distribution of colored triangles form a pattern?
First some background. Until a few weeks ago I had Adblock Plus enabled on Woot sites. When I finally disabled it, I discovered a lot of new stuff on the pages.
Anyway, it appears that the number of users in the 90-100 and 80-89 are always just about equal; as are the 30-39 and 20-29 ranges. The 40-49 range is roughly twice the 50-79 range. The 50-79 range is roughly 3 times either the 90-100 or 80-89 ranges.
Here are the numbers from a few minutes ago:
90-100 (376) 30-39 (4,150)
80-89 (375) 20-29 (4,154)
50-79 (1,126) 1-19 (7,899)
40-49 (2,271) 0 (81,908)
Has anyone else noticed this and has it been this way for a long time?
