Don't worry about it , it is far more important that they are all as close to the same readings as possible.
It is a measurement of the vacuum at the intake manifold and since the manual does not state what revs the vacuum is to be set at the figure is meaningless. Many machines have the vacuum set at a very high idle as the vacuum reading are to low to read properly at tickover speeds. I have found on the Fazer 400 I have to set the idle to 2000rpm to get readings with the Morgan carbtune.
As longs as you can read the measurements and they are all as close to each as possible then check the TPS setting and ride on
