I hate these uncategorizable types of questions!
Which Aikido are we talking about? Federation? ASU? Ki-Society? Mine; yours; Jun's; O Sensei's?
Aikido = 5.28xMartial + 3.6xDance - xy/2r
(where x = distractions from training, measured in units of time; and y = % of caloric intake, of fatty foods for that week. r = the ratio of years' training to your goals)
