Just lookin around at the vanity addresses:

Burnside has said:

1QKtEyRAUwVgod738WuEwUWcKGyRMMRea5
17ZRNXsS9AvzCQJaEmUJHHCDH5xLdvyxr8

were the deposit addresses.

I found 1Garr2555P4oiAaLQqXkcdAKGg4SMt3RZS in the taint analysis of the top address. I'm assuming this is his personal address?

Anyway.

The only thing I find fishy is that Garrett said he would be using 1cogHCDW6ScMxuXQ5DNxS6LvLRVP18vBt for the HHTT pool, yet there have been quite a few transactions from the HHTT fund pool to 1Garr2555P4oiAaLQqXkcdAKGg4SMt3RZS account.

The 115tTroRo3B9ZDQ6ATJGDCHcNEVbjJoZnF address seems to be some kind of payout address from ASICMiner shares.

The addresses we will be switching to are:

1cogxXyYU2EXEbdcV9j18PWenRU7gAjt1 for Slush's pool.
1cogHCDW6ScMxuXQ5DNxS6LvLRVP18vBt for HHTT (becoming effective this evening)
1cogtXwSq9pZLfNsiFv48UFzjdEtZGTN7 for Eligius  (becoming effective this evening)

Simply looking at historical charts of the first two balances:

https://blockchain.info/charts/balance?address=17ZRNXsS9AvzCQJaEmUJHHCDH5xLdvyxr8
https://blockchain.info/charts/balance?address=1QKtEyRAUwVgod738WuEwUWcKGyRMMRea5

These charts show no data into October/November.

Looking at Garrett's personal address:

There was a huge spike to 800+BTC in September which was probably a withdrawal into USD to buy the CoinTerra rigs, since they accept USD only, which was probably very very unlucky as this was just before the spike in BTC value.

The numbers seem about right - ~900 BTC @ ~160USD/BTC meaning $144,000USD meaning 10 rigs @ $14000USD each (the Dec batch) meaning ~20 TH/s in power which is around the 28TH/s in orders claimed by Garrett.

EDIT: more accurate figures:

888 BTC @ $125 / BTC at bitstamp turns out to be $111,000.

Yesterday, I placed an order for Cognitive from CoinTerra! I negotiated a discounted rate so we were able to purchase 14 2th/s boxes for a total hashrate of 28th/s, to be delivered in January!

which was made on: September 24, 2013, 07:23:28 PM

which coincides with the 888 BTC withdrawal (2013-09-13 00:34:16)

The Early January Batch was priced at $6k USD a rig, and the first batch (http://cointerra.com/product/terraminer-iv-2ths/) was priced at $14k.

For the early January batch, it works out to be 18.5 rigs. I'm thinking that in order to find a buyer for such an amount of bitcoin would ask for a much lower trade price, i.e. ~$110

It all works out, except possibly the October/November dividends.

Burnside's addresses do not have incoming transactions past early October
Garrett's new addresses i.e. prefix 1cog do not have any transactions before December.
Garrett's personal wallet contains some transactions between these times, in particular:

which add up to 0.35 BTC.
