0. Unknowns back to near 10%
After adding Tangpool, BW Pool and "For Pyra", unknowns are back down. Of course, I know little or nothing about these pools, and the identified blocks might not be the only ones they solve. However, it's a start.
For "BW Pool" you'll notice the hashrate seems out of order. This is because the pool has been signing the coinbase for only part of a week, so comparatively few blocks were solved.

1. Historical centralisation of bitcoin network block creation plot added
This chart shows the changes in the amount of the network controlled by the largest block maker, second largest, and so on up to the twentieth largest (should that number of block makers exist during the week the estimate was made).
Solved block statistics table. This table lists all statistics that can be derived from the number of blocks a hashrate contributor has solved for the past week. Block attributions are either from primary sources such as those claimed by a particular pool website, or secondary sources such as coinbase signatures, or known generation addresses. When dependent on secondary sources only, data may be inaccurate and miss some blocks if a particular block-solver has gone to some trouble to hide solved blocks. This will result in an underestimate of the block-solver hashrate.
Note that actual pool hashrates when derived from shares submitted per unit time will be more accurate than the hashrate estimates given in this table.
"Unknown" is not an entity but the group of blocks to which I cannot give attribution using the methods given above. "BitAffNet" is Bitcoin Affiliate Network.
Although I update regularly, I don't correct old posts.
Reused but unknown generation addresses
Unknown generation addresses that are not reused are probably solominers or private mining concerns that don't have share-holders wanting to follow transactions. However, reused addresses are probably from hash contributors that do not wish to remain anonymous. These need to be identified so they can be removed from the "Unknown" group. I'm not interested in identifying those who wish to remain completely anonymous, so I'm not trying to trace originating IP addresses (as Blockchain.info does).

Hashrate distribution: Stacked histogram percentage of network blocks
A visual representation of the "Percentage of network" data aggregated in the table.
Hashrate distribution: Actual and cumulative percentage of network blocks
Another visualisation of the data in the table. The unshaded section indicates block makers with the largest hashrates that control 50% of the network between them.
Hashrate distribution: Heatmap of historical percentage of network blocks attributable to block makers.
The data in the above hashrate distribution histogram is a subset of the weekly data data below.
Hashrate distribution: Daily proportion of network for current block makers.
The next three plots group hashrate distribution into three tiers: The block makers with the largest proportion of the network, block makers with an average proportion of the network, and block makers with the smallest proportion of the network.
Because the data is a daily summary, the kernel smoothing shows quite clearly the variance in hashrate distribution that occurs in block making. It will also show the intra-week hashrate movements which were previously unavailable.

Comparison of transaction fee per block
Block makers that consistently perform better than average are attempting to earn as much from each block as possible, which probably means more transactions per block and a better functioning network.
Block makers that consistently earn less than average transactions per block are either including too many low priority (no fee) transactions or are trying to reduce their orphan rate by reducing the size of their blocks.

This chart shows the changes in the amount of the network controlled by the largest block maker, second largest, and so on up to the twentieth largest (should that number of block makers exist during the week the estimate was made).

I'm terrible at proofreading, so some of these posts may be worth quite a bit to the keen reader.
Exceptions:
- Errors in text repeated across multiple posts: I will only pay for the most recent errors rather every single occurrence.
- Errors in chart texts: Since I can't fix the chart texts (since I don't keep the data that generated them) I can't pay for them. Still, they would be nice to know about!
