I feel if people concentrate on competion practice too much during training, there aikido will suffer in some way. This is because inveitable form suffers during competion, and there are many tecniques which are prohibited during the competion.Thus if these tecniques are not allowed, then people who pracitce competion training in normal classes lose a section of the art. If you want to test your skills in aikido, do a jiuwaza type randori, with multiple attacks and weapons etc. Let uke use any attack, this will test your skills. We practice this alot in training.
