Wouldn't it be better to do BOTH tests? The static one first to see if the ABS is functioning at all, and you'll feel what it feels like, then if the ABS is functioning and you now know what it's supposed to feel like ... so when you test on a suitable surface you'll have a better idea whether the ABS is functioning or the rotor is warped, or both.
