This is true. Those are accurate but they are hard to use if you aren't standing right over it to read it correctly. I have on old Craftsman like that. It belonged to my dad who bought bit in the late 60's. I absolutely trust it and still use it when it's practical.
The only time I use a beam style torque wrench is when setting the pinion bearing preload in a diff. You use it to read the turning torque as you crush the crush sleave. That's the only tool you can use for that that I know of.
