Yeah, that.
Others can discuss the difference between a glass rod and a candy cane breaking but as close zero creep / movement as possible. The difference between putting pressure on the trigger with the intent to fire and gun-go-bang should have no perceptible movement. Ideal IMO is not less than 2lbs, not more than 4lbs.
I don't see a strong case for a "rolling break" in a SA trigger. I guess if you want to start a fight on the internet talk about staging the DA trigger instead of using the SA trigger. There's your rolling break. Is that something people even argue about in the year 2022? IDK. Colt essentially making what was a 2-stage DA trigger that lent itself quite well to the practice for most of their dominant period in the domestic revolver market certainly makes one argument. A generation of LEM-traumatized DHS shooters could make the counterpoint.
