I rather like this particular ICO format. It reminds me of how Augur REP, one of the earliest Ethereum ICOs, was handled (except without the whole stretching for a year part).
I'm hedging my bets by using about 1/4 of my allocated EOS funds to buy in during the first 5 day period, then will spread the rest out over the whole year, waiting for days when there doesn't seem to be much interest.
If the prices increases when it hits exchanges, I plan to sell enough to recoup my initial investment, essentially getting a batch of EOS for "free", and then roll that money forward into future distribution windows to get more EOS at hopefully cheaper prices.
Will be interesting to see how this plays out, and how many people get it from exchanges vs. the daily distribution.
