Help with a profile callout

Hello all!

Fast question for the following callout:

The callout is for controlling these 2 "L" shaped pockets(?!). This is actually half the part as there is a mirror half on the right side (thus the 2x and 4x designations on the basic dimensions). I am a bit confused as the 2.6 basic dimension is restricting translation of the vertical planes while the callout has no datums in the callout. Is this correct?

How would you control this in a no CAD program? Thanks in advance for your advices

neil.challinor So I am right to assume that by controlling them simultaneously the 7.8 gets involved in the profile (while 2.6 is neglected) as far as pcdimis calculation is concerned right? There is no other callout to control these pockets. For me strictly following the callout, we need to not measure them simultaneously. The basics as they are, are a mistake imo and either datums should be used or change the 2.6 to follow the 7.8 tactic (dimension the horizontal distance between the mirror vertical planes) and evaluate all 4 pockets at the same time. Thoughts?
