PPF

Every time I convince myself that I understand most everything (ha,ha) and
just need to memorize the various formulas and lists, I find myself stumped
once again:

Does anyone know why the PPF is computed differently for Homan and the Static
Method I.

The PPF for Homan is :
(1+(Avg annual increment/Fitted avg rel)*(Tempering Factor))^(Trend Period)

The PPF for Static Method I is:
((Fitted value one yr beyond proposed eff date/
Fitted value at midpt of curr period)*(tempering factor))+
((1-tempering factor)*1.0))

Thanks,
