The snap-on website says that their torque wrenches are accurate +/- 4 % as
long as you're not reading in the 20% or less of the scale
http://buy1.snapon.com/catalog/OBJECTS/29000/28910.PDF
I read that as if you have a wrench with a scale of 10-75 ft/lbs, it's not
accurate all the way up to 15 ft-lbs (or should I say 16% inacurrate to 15
lbs)
So, is there a cross-over of the inch-lb to the lower end of the ft-lb
scale??

PS--The most accurate craftsman torque wrench listed has an accuracy of 3%
for click-type and 4% for bar-type.

This sounds like the "clicker" type, which I have. Does anyone have
any experience with the type with the needle and scale ? which is more
accurate? Durable?
Ah, talkin' cars and wrenches again...
