Thank you for your interesting comments, Dana.
I can always rely on you for incisive and opinionated commentary about stellar evolution and H-R diagrams!
I am still cogitating and pondering about this paper.
(currently I am just a little distracted with about a million other scientific and technological topics!)
Best Regards

Good point about the very small numbers of stars used in their study of N6752. Also, reading your comments below, I see you have made the important point that it is quite possible that their derived Color-Magnitude Diagram (Hertzprung-Rusell Diagram) is in error and/or their model is in error.
Stellar evolution models have a habit of being 'further refined' with time; isochrones tend to be quite approximate and model-dependent.
