I don’t think what you say Anna contradicts what dxu said. The obvious simple strategy is now being tried, because the galaxy brained strategies don’t seem like they are working; the galaxy-brained strategies seemed lower-variance and more sensible in general at the time, but now they seem less sensible so EY is switching to the higher-variance, less-galaxy-brained strategy.
