I'm sorry but I'm still trying to understand exactly what you're looking for. I tried to explain the "as detailed" and the "built up" tolerances the best I can.
The dimensions shown below on the far left are based on the "for example" dimensions that you posted initially. I took those "for example" dimensions and applied them to the actual prequalified "as detailed" tolerance ranges and the actual prequalified "as fit up" tolerance ranges using your "for example" prequalified PJP joint designation, B-P3-GF that you posted initially. What I show in parenthesis is the acceptable prequalified +/- tolerance ranges for "as detailed" situations and the prequalified +/- tolerance ranges for"as fit up" situations.
Basically, the "as detailed" tolerance range below can vary between what's actually shown on the design drawings to what's actually shown on the detail (shop) drawings by the tolerances I show in parenthesis, and the "as (built up) fit up" tolerance range below can vary between what's actually shown on the detail (shop) drawings to the dimensions of what's actually been fit up, by the tolerances I show in parenthesis.
Root Opening
Root Face As Detailed As (built up) Fit Up
Groove Angle
R = 0 + 2, - 0 (can be detailed + 2 to 0 from design drwg.) + 3, - 2 (can be fit +3 or -2 from detail drwg.)
f = 3 min. + U, - 0 (can be detailed 0 to unlimited from design drwg.) +/- 2 (can be fit + 2 or - 2 from detail drwg.)
a = 60° + 10°- 0°(can be detailed + 10° or - 0° from design drwg.) + 10°- 5° (can be fit +10° or - 5° from detail drwg.)
