I would not expect this to make much of a difference on a table which is perfectly correlated with the index. You would have to create an accounts table which is randomly ordered to have a meaningful benchmark of the eic parameter. I don't know why the default for eic is 1. It seems like that just turns on the eic mechanism, without any hope of benefiting from it. Cheers, Jeff
