I initially wasn't going to respond to this, because I know it's pointless to argue with you, but you made so many wrong assumptions in there that I feel compelled to.
If you got from that post that
A: it's a complex scenario training, (running, and turning to attack if you can't escape, is far from complex)
B: I'm giving them false confidence (when you try to run and the person catches you each time they chase, that's telling you you need to work on your running more)
C: that the street almost certainly won't be safe (fyi it's probably about 30-40 yards, and by that point, like you stated, is when you either got free or when you realize you won't), D: this is suggesting that they should not practice running (if they are slow, it'll just reinforce that they should be running more),
E: I'm saying they should run every time (it's one option), or
F: that you should run if you're not fast (nowhere did I say that)
Then you clearly didn't read the post very well, or are imagining something entirely different than what happens.
why does it need to be an argument, rather than a debate or a discussion?
I'm not dissing your scenario train, just most of them as being staged to the level they become completely unrealistic and the more complex they are the more contrived and unrealistic they become and at the point where you have multiple people some hidden who may or may not attack dependent on the script, it's certainly complex.
at real level if theres 4 people in a narrow alley way between you and safety you not getting out of there unless you have some very well developed rugby, american football ice hockey skills, any s scenario that ends with a successful escape with out such skills is not realistic at all. someone isn't trying hard enough to stop the escape. are you running scenarios that constantly fail to get you to safety or are they contrived and give a false level of confidence .? it has to be one or the other unless it's the New York Broncos your training.
what's really missing from this is why are they chasing you, it really really matters as to how much effort they are likely to put in. a minor flash point they wont chase you more than 10 yards as a token effort if at all, they will just call you a coward as you disappear from view. if you've spent the evening winding them up, chatting g up their girl friend or other really annoying them to the point they have decided to cause you physical harm, they they will really put some considerable effort in and as hurting you is there motivation, getting to a busy street wont put them off at all, if there still in range they will continue to chase you down, but if there not making any meaningful gain your your lead, they will stop after a 100 yards or so, probably unless they are really really annoyed
the whole turning and fighting thing, is a bit iffy, you cant actually run flat out and look over your shoulde, so you dont know how much of a lead you have, stopping if your getting away is stupid, stopping if there about to kick your legs away, takes really good timing or they will just collect you as you stop or run past you, which then puts them between you and escape
the real problem is a group of young men, running will provoke them to chase, even if most of them have no idea what they are chasing you for, and the chances are a some of them can actual run at at speed, they will hunt you down like a pack of wolves, turning and fighting is of little use if theres three or four of them in close contact. really if they are not actually chasing you, walking away is a lot better strategy, at least till you can turn a corner then legg it
