I think there's a misunderstanding somewhere... I meant to say that when you judge a delegate, they can will correct you immediately if you do anything wrong. It is a good way of learning the basic rules and regulations; if you get corrected once, you won't make the same...
And... That's exactly how void cube parity algorithms work! Some of them only swap the center positions and the others twist them and swap their positions simultaneously.
EDIT: You probably already know about it.
The colour scheme seems to be different, but that won't be an issue.
Take a look at all of the 6 center pieces and note their colours. You don't have to worry about the patterns.
Then, google a tutorial. While following the tutorial, treat your colours like they were standard...
Well, as I've said earlier, there's no harm in using heavy lubes if you wash it out periodically.
If you clean the pieces thoroughly every 1 - 1.5 months, your cube will remain healthy for a long time.
