A 20% to 100% range is pretty normal for click type wrenches, and most shops I know have been running them that way forever. The bottom 20% is where the spring tension gets sketchy, sure, but panel screws and small hardware callouts are usually a range spec anyway, like 12 to 18 inch pounds, not one exact number. Half the time those screws are getting snugged by feel and a torque seal check. Unless you were trying to hit a specific number down at 3 or 4 inch pounds, I would not lose sleep over it.

That bit about "fast at one thing instead of good at the craft" hits home. I read an old post from a blacksmith who said he did nothing but hooks for a year and called it his grad school, because by the end he could feel the metal move before he hit it. Two years of openers gave you a skill most folks quit before they get, so maybe the move is one new thing a month and keep the openers for fun money.
