The text of the spell states that it grants the subject the fast healing ability. The subject then heals by himself.
The point of suggesting your argument was one of semantics was to allude to the irrelevance of the distinction between saying that the {spell grants fast healing and the fast healing heals you} and {the spell grants fast healing meaning the spell heals you on a per round basis}. No matter how you cut it up, the spell is healing you - it is a Conjuration [Healing] spell! Whether you say that the effect of fast healing is healing you or the spell is healing you - you are saying the same thing.

If someone Shapechanges into a creature with Fast Healing 5 [Su], the Shapechange spell is not healing them 5 points each round. The Fast Healing ability is healing them. Shapechange just provided access to Fast Healing.
That's what Vigor does, per the text of the spell.
You are right, shapechanging is not healing them. In fact, this gets to the fundamental point I am making - the effect of shapechange is to change your form and is a transmutation effect - which incidentally would make augment healing ineffective anyway. The effect of vigor is to heal you via fast healing. If the fast healing was intended to not be a magical healing effect of the spell - which, again the text clearly states that it is - the spell ought not to have been in the conjuration (healing) school.
Andrew Finch is directly contradicting the text of the spell saying that it is not healing and the fact that the spell was not changed to a transmutation effect speaks the loudest to me.
Hyp, I would agree with you 100% if I was interpreting the spell to change you in some way distinct from the magic of the spell. What do I mean - if the spell induced a transformation - i.e. transmutation - and then the result of that change caused healing like with shapechange I would be on your side. However, the stat block is distinctly different from that interpretation.
No matter if I've managed to convince you or not, for a moment concede the argument to me and argue for or against allowing the benefits of the feat to apply on a per round or per casting basis.
If the feat only applied on a per casting basis - then I would think the recipient would gain the benefits of the boost immediately upon casting - so 6 points with a Vigor, mass lesser and then 1 point every round thereafter.
However, as you suggest Hyp, there is no initial healing. So I would be inclined to not have the spell heal anything to begin with - it is +2/level of the spell to the damage healed. In the case of Vigor - it heals damage every round.
I really want to say that the most accurate interpretation is 7 hp's/round with the aforementioned spell. Certainly this is a pretty big loophole and may require houseruling but that is another issue.
