The BTC blockchain is only a store of blocks, it contains no actual statistics of any mining.
What I mean by this is that you need hundreds if not thousands of blocks in the BTC blockchain to estimate a pools hash rate based on blocks found (and that also ignores stale blocks and orphans) Block finding is (mostly) random luck, so to reduce the (mostly) random luck in a calculation based on those (mostly) random luck events, you need a lot of data. The reason the difficulty changes every 2016 blocks is because it takes a lot of blocks to estimate the network hash power with any accuracy - but even with 2016 blocks it's not very accurate.
... most pools hash rate varies per block found, so using a set of (mostly) very random data to estimate a moving target is not gonna be very accurate for most pools other than the top few around 10% or more of the network.
