Another question popped up as I've been going through the generation procedure for a new sector.
So, to add a little flavor to my system generation, I've been rolling the standard age dice (D6x2 + D3-1 + d1000/1000 Gy) and, if it exceeds the MS lifespan for the Class V star, do a little jiggery-pokery to taste with the individual dice results to come up with a percentage of MS lifespan (which may end up >100%).
Now, that said, when said Class V star is turned into a Class IV by that procedure, I've been upping the Mass (like the moron that I now realize I am). But, some reading I've been doing shows that I shouldn't be increasing the star's mass at all, which makes me think I've been interpreting the chart on p.17 wrong.
For stellar mass, is it the intent of the chart on p.17 that the listed mass for each listed spectral type is the mass of the star through its entire life up to that point? If so, should I then change the spectral classification of said star based on its mass, instead of (as I've been ignorantly doing) increasing mass to fit the spectral classification? (Of course, as I'm typing this, my brain is going "Yes, that's exactly what you should be doing!")
