Sorry Mr. Cat shooter didn't mean to hurt your ears by yelling so loud.
I corrected the size of type so as not to hurt anyone Else's ears. 
I have no idea what Industry standards are but the ones I have and measured are not all the same dimension very close but no cigar. Maybe my measuring equipment and my ability to use them accurately has gone south on me
. No doubt they are within spec's. what ever the + and - tolerances are. 
I have several doubles, Just got the extras put away.
