By doing a long sale split into windows they will sell at market value.
I somehow agree with you in theory. In practise they can change plans per week of batch selling. I'm not to knowledgable on Crypto ICO's, but what I see on Poloniex when pulling up the coin value charts from day one, most of them where really high up and now worth only a fraction of it. Not for the older coins, but for the newer ones. Anyway, time will tell what will happen.
EDIT:
Interesting post you shared. Option 6 is the EOS option as far as I understand what EOS intents to do. But this doesnt change what I mentioned above in this comments. Plans can be adjusted. Hypes can be powered up. Crypto is in hype, and EOS is in hype, that is double hype. Anyway as mentioned before as well, time will tell :)
