I would watch how you put it though. One could argue that as you do full contact your techniques are proven not to work as after five mins in the dojo there would only be one person standing and you would not get anywhere. That is not a dig I honestly know there is more to it than that and I have the up most respect for full contact styles, we train full contact once you get to about 3rd kyu in mostly shotokan though its very rare for some one to get hit as by that time you have learned to block like a jedi .... oj . The whole point of kata is proven techniques that work. Some further evidence of its working is shown when we practice the bunkai . Also after being jumped in an under pass in November by 3 people, the fact I successfully defended my partner and myself showed it does work (thank goodness). It really highlighted something to me. My partner has not been doing karate that long but thanks to being really fit and previous kick boxing experience at 13 she was doing well enough that she should have kicked bum. How ever she has not been in any comps yet! The result was she shut down (literary lay on the floor and turned off) almost going into shock. We spar often in the dojo but It does not matter how you do it, who you do it with, known or unknown, to me competitions are the only way you can train for those high pressure situations and learn to keep your nerves. Spar in the dojo all day everyday full contact no contact makes no blinking difference if you cant handle the pressure of a even a 100 people watching you. Just spent an hour trying to post that couldn't figure out why it wouldn't let me post it . I forget the other word for bum can be sweary to some people .... doh
