I checked our sample and it is definitely 24 degrees. Would not be the first time an OEM prints one spec but actually produces another. Not saying that is the case, but it has happened. Could be the sample I received was an original and they decided to change the spec, I just don’t know. If I plug in 26 degrees in the formula, and assuming all the other numbers are the same, the MPF goes to 902 vs the 924 (24 deg.), which is 22 points different, but statistically insignificant. The only reason it will vary slightly is because the tangent number used in the formula is different for each loft. Still an Ultra Game Improvement iron whether the loft is 24 or 26 degrees.

The MPF formula does not include loft. See the following Link:

24 vs 26 is probably a type.

Sorry for the bad info above, I review the info and see that the Tangent of the loft is used in detmining the VCOG.
