The "radian" test (we've messed with it in the cordic topic) runs in rad mode and does 9deg>rad, then the actual test runs, and then rad>deg. The "degree" test runs in deg mode, internally it most probably does deg>rad and rad>deg with each trigo function used. So in the "degree test" there is ~6x more conversions involved than in the "rad test". I've updated my post above for clarity. My current understanding is the diff comes mostly from the internal conversions. Considering the internal calcs run 39digit (thus the conversions) it seems to me the diff is rather big.
