I'll be testing with Beta 13 and not 13b though. The reason is that I already
have the results of the default settings of Beta 12/13, as well as others. There
is no reason to presume that the parameter will work better with the hash change
he made compared to others. Otherwise I'd have to re-run the defaults settings
of 13b as well.
