Interesting video, but I'm wondering about the aeration technique. I remember seeing one video where they aerated with pure oxygen but before that they had aerated the mix by shaking, pouring water in quickly, etc.
Now, in theory oxygenation should work best if you have wort which has very little disolved gas - if you've already agitated the mix then you've mixed in air (79% nitrogen) which the oxygen is going to have difficulty driving out. Most of the oxygen you aerate with is just going to bubble straight out.
Theoretically, the best technique should be to boil the water to remove nearly all gas, then chill (preferably sealed), then mix into the wort agitating as little as possible, then bubble the oxygen through; finally, seal in a carboy leaving as small an air gap as possible so that there is minimal gas exchange with the air sealed in the carboy.
Hey, I might be a newbie brewer but you learn a lot about gas laws as a tec. scuba diver
