It doesn't make any sense:
- the FCF is datum A
- the FCF states "over datum A" (?)
- the FCF relates back to datum A (and B)
- we have an indication of where datum A is with a length as well and it is not where the distance and length tells us because the FCF states otherwise
Suggestion: call the designer and have them clarify what the intention of the callout is, maybe then you could do a proper evaluation, not neccessarily the one that is on drawing.
