Interesting post...
Shaofutzer, that's an interesting story. I won't deny your claim - you may well do this - but I would like to see you do it.
I think you may have hit a nerve with your statement
Is it because some people just don't have the ability to do it so they claim that it's dangerous, irresponsible, and ineffective?
I've a feeling many folks are in denial someone else can do something they can't do and/or
have been conditioned to believe cannot be done.
Most 'controlled' ranges won't allow it - takes up too much space and the possibility of some form of injury leading to a lawsuit - and therefore most folks can't even attempt it at slow speed. Even in most 'practical' shooting, movement is done between shots, not while shooting. It is 'just not done'. And, like shoulder holsters and uncovered trigger guards, when one or two 'authorities' pontificate against
that protocol, all true believers accept it Holy Writ.
Still, the concept is not new. The Mexican Defense Course (the real one, not the SWPL adaptation) required six shots while walking forward. I cannot explain the rational, but it has been part of the course since prior to the 1970s. The old South-West Pistol League (SWPL) incorporated a 'lateral' movement (right to left or left to right) into some of their courses. Usually this is performed at a slow rate of speed, with emphasis on not injuring one's self or any of the range officials or onlookers. Customs and Border Protection (CBP) uses some lateral or downrange movement in 'practical exercises', but a range officer is always close enough to 'control' a shooter - especially when moving backwards.
Shaofutzer, I wish you the best in this. Do NOT allow anyone to rain on your particular parade. DO, however, be as careful as you can. Falling and cranking off a round while falling or bouncing as a result of a fall is not best practice in any event. You probably knew that already.
If I can find a place to try it - safely - I may experiment with it as well. However, my knees are bad these days and I don't jog at all any more... I probably won't do any serious running, either.
