I'm missing something here.
Yes I see that X CoP = X pearls... but where are the 10 water gems comming from every turn in order to increase the number of CoPs (by turn 4)?

Are you assuming a water gem income of 10 water gems on turn 4? That's a pretty big assumption for most nations. Furthermore there are plenty of useful things to do with such an income.

Again I understand that the clam ramp-up can pay off eventually, but I fail to see how it is a "broken" strategy, let alone a particulaly good strategy (IMHO). It's a very long term investment that ties up valuable resources. If you are going to convince me that this is a broken stragegy you will have to be more convincing.
