Torque wrench click on a carbon stem, felt wrong and it was

I torqued a carbon stem on my gravel bike to 5 Nm this morning with a new Park Tool TW-2 and the click felt soft, not the usual snap. Checked the bolts with another wrench and they were at 4.2 Nm, so the calibration is off by 0.8 Nm. Has anyone else had a torque wrench go out of spec after a drop, and did you send it in or just buy a new one?

My old beam wrench from Sears is still dead on after 15 years, but every digital thing I own drifts eventually. Guess that's the pattern, the more complex the tool, the faster it forgets how to do its one job. Send it in if you can, but honestly for the price of shipping you're halfway to a new one anyway.
