Here is some more "food for thought".
The typical attacker on the street may have malicious intent, but is most likely not a skilled fighter. They are typically expecting an easy target, not someone that is going to fight back....and certainly not someone who is a martial artist. So if you survive that initial attack and end up in more of "squared off to fight" situation, chances are you will be facing someone less skilled than you and that will be taken by surprise BY YOU, because they will not be expecting you to put up any kind of real fight. So in some respects, once you overcome the fear and nerves and survive what was likely a surprise attack or sucker punch, this should be easier than facing a skilled competitor that knows your style and is expecting you to "bring it." So if you can't make your martial are work in a hard sparring or competition situation, how do you expect to make it work on the street?[/QUOTEI'd sayou try information to build a very narrow set of circumstances, certainly if you face someone with no fighting skills, poor fitness and slow reactions then you have every chance of winning, but people like that don't normally attack peopke in the street, unless they are drunk and or have big mates with them.
here are people who have been fighting every week since they were five, by the time they get to 25 they have built up a set of dependable fighting skills, they may not have many techniques, but they are proficient in what they do, if they have also been weight training, work in a manual job or play sports, then they will be quite a handful,
I'd say a street attack is far more likely to come from the second group, if you thinking you won't get attack by someone very strong, very fast who can throw a good punch, then your living in fantasy land.
