I recently received my new 714 AP2 irons, 5-PW, that were ordered 1/4" long. When they arrived, they were actually 1/2" longer than the Standard specs posted. They are also longer than my 712 CB irons by 1/4" which I thought were 1/4" over standard. Are the standard specs measured from the end of the shaft or the end of the grip (which would add an extra 1/4")? Thanks
