The problem is, unless it's an actual torque wrench these clutches are allll over the place. There's a reason they give only some arbitrary scale, and often enough they're so unreliable that the same electric screwdriver / drill will produce different torques for the same setting depending on the battery SoC, the power setting and the cleanliness of the thread in the wood.
I've found the most reliable way for IKEA furniture is to use an electric screwdriver for the bulk of the work and use a manual screwdriver for the final 1-2 turns. Everything else is just asking for trouble, especially the screw "overshooting" because the particle density at one hole is randomly (markedly) less than at the hole you calibrated the screwdriver with.
