Different profile tolerance at each end of plate

[bxbzq]

Hi,
Details see attached. I use the idea of fig. 7-27 in '09 std on profile. Does it make sense to you? The larger profile tolerance on surface B is mainly because of process variation but functionally it is acceptable.

I'd say the graphics were "intentionally incomplete".
The tolerance zone is attached to outline of the part, so outline may have to be basic dimensioned; and this is where A datum will come into play... someplace.
