Well, the great Musashi believed that one man is the same as ten thousand...in this situation, we would be satisifed with one being the equal of seven...
You can have the best training and be a great strategist, but if you cannot work your strategy into the situation at hand...you are SOL. The value of training and strategy are only relevant if you can make it work at the time you need it. Seven determined attackers leave 99.99% of people in deep doo-doo because most of the folks that have the training/strategy skills have very little experience in real life, full speed, dynamic encounters where they are required to apply thier skills to the situation at hand.
If you can work your way to the gun, it is your best/only hope...if you cannot talk your way out of it.
