Torque wrench calibration drift caught after 200+ carbon builds

I trusted my click-style torque wrench for two seasons until a customer's seatpost clamp cracked at 5 Nm. Checked it against a beam wrench and it was showing 6.2 Nm, that's a 24% overshoot. Now I test both my wrenches every January with a simple bolt fixture, costs me ten minutes and saves a lot of frame warranties. Anyone else found their torque tools drifting faster than the manual says?
