Front derailleur braze on angle

So I found the issue with my FD and dropping the chain.  The clip on the frame for the FD braze on was slipping changing the tilt of the FD.

Does anyone know what angle the clip should be?  On most frames it looks like it's in line with the seat tube.  However seat tube angles vary a bit.

My road bike is a 73.5 angle and the clip is at the same angle but my TT bike seat tube is at 76 degrees.

I know that this might be a weird question since most FD are either a set clamp or the clip for braze on's is riveted, where mine is screwed in.

Thanks,
Stewart
