So looking at the rich list you have essentially given 4-5 people control of about 25% of the total coin supply if they play their cards properly and more if others don't.
I normally try to stay positive but find this information very disappointing.
Come on... give him a break. The information is all there on the OP. It is not his job to spell out all the possible outcomes of every possible strategy. That's the whole point; for the people to figure out the best method themselves. You could sell your seeds on the second day (while everyone is staking, and hardly any sellers), then buy on the 4th day for real cheap and stake everything you bought for 3 days. For all you know, the guy staking till the 7th day will have a lot of coins, without any buyers on the market. And those trends (if any) are visible from far for the trained eye. No way is someone going to stake to get 25% of the coin supply, for an overall net loss.
