Understable seems to describe the same throw creating a rightish turn or a potential turnover.
That leaves STABLE.
As a psychologist, STABLE in a person leads one to believe that variance is low, and extremes in behavior are not usually in evidence.
I originally thought a STABLE disc was one that flew basically STRAIGHT -
With little fade or variance one way or the other.
Yet it seems when people say a disc is STABLE, they mean OVERSTABLE.
Why don't they say OVERSTABLE??
Sorry for my ignorance, but it seems quite confusing.
Your understanding is correct. Stable means straight or resistance to turning over at high speeds. Usually, the discs that are resistant to turning over at high speeds also have a lot of high speed dive or fade. So, it is true that an Ape is stable at high speeds, even though it is overstable at low speeds.
