"The Direto does actually contain a power meter, called OTS (Optical Torque Sensor), which is rated at +/- 2.5%. That’s the best claimed accuracy we’ve seen in a mid-range trainer, and only slightly below what we see in most high-end trainers which is usually +/- 1-2%. Elite recommends you calibrate this occasionally using a quick and simple roll-down procedure. Note that no other mid-range trainers have a power meter. Inversely, note that having a power meter doesn’t guarantee perfect accuracy. In fact, the KICKR 2 and KICKR 3 showed that ditching a power meter could improve accuracy since it was one less component to break during shipping (which is what was occurring for KICKR 1 folks). Either way, that’s not really an issue here with the Direto as you’ll see in the accuracy section."
