Andres:
My rough-and-ready approach predicts the TL 2/3 down the median
as seen from the vertex (iow: at the CG) which it is - or at least rather close.
In your diagram, it certainly is within the 99% ellipse.
Could this be just a random coincidence?
Is there an counter
example, one in which my choice of the TL would be far outside that ellipse?
If it is not by coincidence then the probability of its being within the Doch must be bigh.
Regards

An example
for 4 LoPs: see the attached animation for the ellipse of conficence of 25% 50% 75% 95% and 99% prob.
Error:
S = 0.0011
sigma = 1.3999
sigmaB = 1.0029
sigmaL = 1.0499
