I think it all comes down to each individuals.

When I went to a new dojo in vancouver there was that beginner who was screaming like crazy...while we were doing basic footwork...It was kind of funny!He was screaming soooo much I don't think he was actually concentring on his footwork. My friend overheared him talking with others from his group and at one point the guy said "is there such thing as too much kiai?" hehe soo funny

I think showing courage/spirit is almost as important in kendo as to use good waza. Sometimes in front of some opponents for differnet reasons I'm scared . I can't go for men uchi. I lose courage...so I end up losing. But when I do kihon practices I can easely/very well do my stuff against the same person..
