My suggestion is that you make your frustrations known to AGMA by sending them an email outlining your frustrations. To my opinion there is no way to actually touch the tooth at all points using a ball or cylinder, therefore this type of test may miss high or low points and give less accurate x88. To calculate the maximum dimension over pins you had to use the TTCE, the tooth thickness tolerance Y and tooth thinning to achieve minimum backlash.
I think if you do not have a master pinion to check out TCE then you would have to default to the element method of checking w88 gear.
