OCI Commercial Intent As Applied to CPA

I have been using commercial intent to analyze keywords for PPC to product offers as OCI gives a fair valuation as to the intent of the keyword search.
I had a passing thought though, would commercial intent apply the same to a PPC to CPA transaction?
Before you flame me, I know the simple answer is that it would depend on the offer. However, a CPA conversion is fundamentally different from that of a physical product sale.
Yes, I’m over analyzing, but does anyone have any thoughts on this, or maybe insight as to how one might apply the commercial intent value based on a particular offer?
