Guys,
You are getting tied up in semantics.
Look back to the original post for a second.
This could have relevance for pilots wishing to reduce costs of maintain PPL rights (12 months preceeding rating expiry 12 hours flight time of which only 6 has to be PIC).
Of the 12 hours required for revalidating a SEP class rating, 6 must be PIC, and one must be with an instructor. This leaves 5 hours which aren't specified.
Is anyone suggesting that those 5 hours could be satisfied with P2 time on a PA28/C150?
If you look back to the original post, I think you'll both agree on the substance
