Aiki has a way of looking like that when there is actual resistance.
+1 on that Matt.
A lot of Aikido-ka find their structure comes undone under the conditions of Tomoiki/Shodokan Aikido. A lot of Aikido looks good in demonstration and a lot of people can supposedly demonstrate their Aiki ability except when placed under non-cooperative resistance, where many times it duly falls apart.
Whatever these Aikido-ka lack in the above clip, the methods used in Shodokan/Tomiki will give them a clear signal of where they are going wrong. The idea of resitant randori in Aikido, whether in a competition or in class, is IMO the best way to test posture and "aiki" skill. Through such testing a student may further help develop not only their own skill, but also that of the people they train with.
Although this is a competition clip, the core idea of randori has been to test weaknesses in a persons Aikido and help others identify weakness in their own Aikido. So it the primary goal isn't so much "winning", it's learning.
The competitions are just a further part of that development process. It's not everyones cup of tea, but IMHO it is one of the better ways to train in Aikido.
