Phobos is tiny, roughly 27 km across at its longest and 18 at the shortest. Its mass is about 1,8 * 10-9 times Earth. So yeah, the escape velocity of Phobos really is measured in meters per second. The velocity needed to achieve orbit is considerably less, though I can't find good data on it and Phobos' irregular shape complicates matters further, but it should be around 8 m/s, which means that a good running jump could get you all the way across the moonlet, or maybe even into orbit! Of course, traction is also a function of gravity, so it may be hard to accelerate using just your feet...

Oh. Sure, you're correct. Sorry for my mistake.
