Let's tackle this another way, and this is directed specifically to Drop Bear and Hanzou.
When you spar...
1)Do you spar with the possibility that other attackers will join the fight?
2)Do you spar with the possibility that the attacker(s) will have a weapon?
3)Do you spar with the ability to use a weapon, conventional or improvised?
4)Do you have the opportunity to de-escalate the situation so the sparring section doesn't even happen?
5)Do you have the opportunity to escape or evade the situation prior to or during the sparring session?
6)Do you spar only in a well lit, open space?
7)Do you spar with a specific rule set that both of you have agreed to abide by?
8)Do you spar only on a dry surface?
9)Do you spar only indoors?
10)Do you spar on stairs, in an elevator, inside a car, in the parking lot between two cars, on a slippery surface that slopes?
11)Do you spar to a conclusion i.e. you have escaped the situation or the opponent is no longer able to continue the attack?
12)Do you spar starting at a position of disadvantage i.e your opponent is standing over you or behind you?
I'd like to hear your responses. Please be specific as to each of these point whether or not their are utilized. Thank you
I'll toss my responses in as well.
1) Sometimes, although not as often as I would like.
2) Yes, but not as often as I would like - I've been neglecting my weapons work lately
3) Yes, but not as often as I would like - I've been neglecting my weapons work lately
4) No. That option is better addressed in scenario training.
5) No to evading prior (once again, that's better addressed in scenario training), but sometimes I set a "victory condition" for one partner to escape the area.
6) No, I've sparred both in confined spaces and in dim light.
7) We do try to make sure the rules are agreed on beforehand, but it's not uncommon to have asymmetric rules - where the participants have different goals and allowable techniques
8) No, I've frequently sparred on wet, slippery surfaces. (this can be both frustrating and amusing)
9) No, I've sparred outside many, many times.
10) a) No to stairs - I've trained on stairs but not done full out sparring for the same reason I haven't done full out open ended scenario training on stairs - if you throw your partner down the stairs someone is likely to crack their skull
b) Not an actual elevator (don't have one available for the purpose), but certainly spaces equivalent to an elevator
c) Never sparred in a car, but it sounds like fun. Hmmm ...I wonder who I can get to try that with me. Anyone in my area want to give it a shot?
d) Not specifically between two cars, but I have sparred outside with obstacles around.
e) Yes. (Tip - wear clothes that you don't mind getting grass stains on.)
11) Sometimes. Depends on what the focus of the session is.
12) All the time. This is a very standard training method.
I'll be honest, some of the options you bring up I don't do nearly as often as I would like. I train and teach at someone else's gym where the majority of the students are training for competition or for a hobby. If I was running my own gym, we'd be doing a lot more sparring in different environments, with weapons, and with multiple opponents.
It does seem like you've got the idea that sparring has to operate within certain confines because that's the way you've seen it at the typical school. It's as if you visited a bunch of judo/karate/TKD schools and noticed that they always seem to spar barefoot while wearing a special uniform and then declared that "sparring is inefficient training for the street because you don't wear shoes like you would in real life."
