Since you're making this claim link to the source, or I have to doubt it as you are saying SE themselves told us how it worked. The wiki's have no info on this, and neither does any dev post I've ever read and while I won't claim to have read all of them I've read most of them. Neither do any guides from bards I've ever read, so your claim looks really dubious to me unless you can provide the source, which you've opted to not do, twice now.
