I wonder if that Hoppe simulation would work if the liquid was at a different level. Or did they just carefully calculate and test different levels and baffle heights and numbers, that gave them the worse/best case scenario in a simulation. Ideally, and in the real world, you dont have a single tank with baffles across it, you have individual isolated tanks that can be kept pressed up so that the free surface effect is removed as much as is possible.
