The simplest expedient is to say that what we are doing is not aikido. To save face we say instead, "we're TRYING to do aikido (the way O'Sensei did it)" even if we have no clue whatsoever how to go about getting to where he and others like him got to. Some of the threads in the Non-Aikido Martial Art discussion forum may be of interest to you in that regard.
