well-applied dry yeast will do just that without oxygenation.

I figure less pressure gives the oxygen more time to be absorbed by the wort. If it's all bubbling vigorously out of the top of the wort then you're wasting oxygen.
I find that this gives a really good fermentation.

Mine is also 0.5 micron.
I find that for 20 litres, 30 second to a minute at low pressure does the job well. It's certainly a noticeably better fermentation than when I was getting by just splashing the wort into the fermentor.
