I recently had a discussion with a CAP CFIG from Alaska that stated they actually tested the schewizer release on there tow plane at 45 degree angle up at 4000 pounds the release pressure on the handle was less than 25 lbs. Now I didn't get specifics as to method or condition of release. But it was his belief that it, as mentioned earlier in this thread, was more of a reaction time issue than ability. YRMV.
