Turns out the EPD stuff does not force any hash table clearing. However, if you run the same test set repeatedly, this should still produce the same test results for almost all positions. There will be some variability in a very small number of positions, because the previous positions was searched slightly longer or slightly shorter the second run due to how time expires and terminates the search. Of course, if you cleared the hash table between positions, you would _still_ see this variability since the search could be almost ready to fail high and run out of time on one run, on the next run it does fail high before time expires...
