Maybe we better start a new thread? Peter I don't want to pollute your thread or is it allright?
Sorry I am cherry picking, you are right, I knew I was on slippery ice when I was looking at your design thru a magnifier. Next time I will change my tone by asking you why you made certain decisions instead of making assumptions, sorry, I must have overlooked it in your building thread. I was trying to examine your pcb layout based on the things I've read and learned so far. That way learning the do's and don'ts, ok, you however, you have the ability to bent the theoretical rules on a clever way by using a disadvantage, for instance the internal resistance deviation, in your favor.
I'm in the stage to interpret the theoretical rules and trying to implement them, I know practice turns out differently because of compromises you need to make. Today I learned something new, I don't have the experience you have, I'm building my knowledge and making my notes. But for starting it's good practice to start with a symmetric layout. I also know there are other aspects that contribute to the current sharing, temperature for instance will probably work in our favour.
Does anyone have the complete pcb layout from the madinverter power pcb? I would like to think about how it could be made better. I didn't say it is the way to go for starters, but probably the best choice of what you can get at the moment if you want to start. I think there were no other designs open source that well documented, besides the ozzinverter.

Here there is a link to the version without the totem pole driver:
