I'm not too sure what the question is. I believe that Pinny lines, in large, mainstream markets (NFL sides and totals, MLB sides and totals, NBA sides, NHL sides) are very efficient.
The edge you can get by basing your plays on the Pinny lean can vary wildly depending on your criteria, i.e. at what point is the lean big enough, at what moment do you consider the market to be stable enough to weigh Pinny against the consensus - and how much of a better price can you get elsewhere.
Playing -105 while Pinny is at -112, which I think is what you're talking about, is most likely profitable, at least if you're betting on one of the aforementioned markets.
This is just my opinion of course. I'm sure others have different views on the matter.
