Tristan gave an answer in the previous post, but just curious, why do you ask?

The Tetrix motor has a speed v torque curve which is more nonlinear than other motors in the FRC kit. If you linearly interpolate between free speed and stall torque you'll get answer for max power notably larger than the true value. For LogoMotion it makes more sense to use a linear interpolation between stall torque and max power (@rpm) for motor calculations.
