What is the mpf of the Bridgestone J15 CB

I would be curious to this as well as they are what I own and play. I’m willing to bet that they would be higher rated than the J15 DF irons that were actually given an MPF. I think that the older J33 cb has a slightly higher MPF than the DF’s and the J15 CB’s are definitely friendlier than those. They were pretty small.
