Spawn Rate of Named Mobs on Hunter/Forager Cycle

[mwatt]

One out of every ten spawns being a named mob would seem approximately right to me, though it may have even been more frequent on Live (named mobs were simply not very rare). In any event however, a one in ten spawn rate does not seem to be happening in actual practice - despite what apparently resides in the pertinent database column/record.

I understand that actual practice would only approach one in ten over time - but something seems to be wrong. I've been there multiple times and killed enough mobs to have for sure seen mulitple nameds spawn, but I've never even seen one spawn.
