I think this is based on extremely thin data.  The only indication I think 
even begins to be useful is the fact that someone reportedly tried to 
assassinate Tortaalik early in his reign - earlier than 17**2 years into 
it iirc.  Maybe Alexx has made some sense of that part of history, I 
haven't had a chance to look - but either 17**2 is bogus, or two 
emperors/turn is possible, or two Phoenix emperors/turn is possible 
(either of which would make most of the discussion in _FHYA_ nonsensical, 
as T could have resigned the throne to a Phoenix) - or the premise is 
wrong and the goblets were intended to disable T leaving the Throne weak.
