Good to know, thank you!

If you use a RM curve you can calculate all those values.

Yes, if having the curve. I was trying to think of ways to have a limited set of numbers to compare with. Agreed that the curve itself will always have more information.

About the resistance to heel at 0º I don't understand what you mean. You have to explain that better. At 0º the boat is not heeled .

I wrote it horribly, not according to what I was thinking. I was thinking of the derivative, the rate that stability increases from zero degrees: the slope of the curve. In other words, does stability increase only slowly as the boat begins heeling from zero degrees, or sharply? A single number could give a reasonably good picture here.
