Like I said, #1 is the cover, OP is second, Naruto is Third, Bleach is fourth, consistantly.
Then Toriko is 5th. Though it varies a bit more week by week with Toriko, it's never lower than 8th, and averages out to 5th.

Though Toriko is a lot closer to 6th than 5th. Toriko, Reborn, and Gintama all have a mean rank difference of less than 1. Naruto and Bleach are about 2 full mean ranks higher. So they're more consistantly third and fourth.
Also Toriko's only 18 issues long so it can warp a bit over time.
Also Bakuman hasn't been on the chart very long so you can't tell where that's placed, but where it stands now it's higher than Toriko.
