Re: Signs of too much cross training.
When your head instructor has noticed you stick out like a sore thumb despite your best attempts to blend in.
The instructors are often correcting each other on what it is that you did before, while being sure they are right.
Accidentally doing the wrong version of a kata or technique without realising. In front of everyone!
Confusing the heck out of the beginners, who think if they copy you, then that must be right. To the dismay of the instructor, who then has a whole line of people below a certain rank doing the wrong thing!
Appearing to be more DUMB than the average aikidoka.
