One thing about analytics: They did exactly that, compute costs without applying them, from the beginning of STEEM even. Oddly, it would have been such a small thing to check up on what the balances and costs would be at time of flip. They probably did that (at least for costs), but they maybe were expecting that once costs started to be applied, the traffic would jerk to a halt (but not bc of negative RC balance, which is what actually happened lol). At that point, costs are high, and only a few resources would be used in the first blocks after fork. Then, as the resource pool inflates due to non-use, the cost curve would drive prices down over time. So, it isn't entirely "bullshit" for them to say they don't know what the equilibrium is. However, they probably could have done some simulations. That would be based on the available RC balances for the users and adding their traffic to consume resources when the cost becomes low enough. That would be actually a kind of fun experiment to do separately, come to think of it.
