Re: Have you actually used Aikido?
From what I understand (and someone answered this much better on another thread, just can't remember who it was), the degradation of fine motor skills under stress has much to do with the increase in heart rate and adrenaline spilled into the system. This can affect fine motor control. However, if you can train such that you can perform under stress, then this degradation would not be much of an issue. Some people are also natural gunsels and do not have this problem to begin with.
