If you want to burn her, remembering the repeating of lifepaths; probably repeated at least one 2-8 times; perhaps another one 2-3 times.
So, looking at age 80… and, say, Noble Lady…

3 mental stat points, 1 physical stat point, 5 general skill points, 31 career skill points, 6 circles points, 5 trait points (one required to be spent on Mark of Privilege), and maybe as many as 15 resource points.
Nothing too scary; really about 5.5 careers power-wise. While not in the rules as such, it’s pretty much true that the 3rd trip on a given LP entry is mechanically just shy of half a LP, and the 4th and later are pretty much worthless except for building resources.
My initial thought was to move to courtier instead of lady 6 (kids are gone, now doing new stuff as hubby becomes ruler-type)
Courtier ___ 6y (60) R 1 (12) C 2 (08) SP 8 TP 2 St -
Courtier 2 _ 6y (66) R 1 (13) C 2 (10) SP 8 TP 2 St -
Courtier 3 _ 6y (72) R 0 (13) C 0 (10) SP 4 TP 0 St -
Courtier 4 _ 6y (78) R 0 (13) C 0 (10) SP 0 TP 0 St -
Courtier 5 _ 6y (78) R 0 (13) C 0 (10) SP 0 TP 0 St -
She now jumps to 3 mental stat points, 1 physical stat point, 5 general skill points, 51 career skill points, 10 circles points, 9 trait points (three required to be spent on Mark of Privilege, Fop, and Rapier Wit), and maybe as many as 13 resource points.
About a 7-8 career equivalent.
If you feel she’s too powerful, charge an extra point or two for her as a full-burn with that many LP.
Now, if she moves to courtier earlier, she’s actually nerfed more, since Courtier is worthless after the 3rd trip through.
