Nitrous plumbing A1A...??..

The bars on the plates have 10 holes facing each direction horizontally there's two bars with 40 holes total. I hear some talk about jetting depends on what plate you have? In my simple mind I think well that bar is only going to get what jet I put in there will let it have? Jetting jetting jetting that is a lot of my questions right now.. so many different jet charts. Some are saying equal Jets nitrous and fuel and summer saying bigger jets for nitrous and just a bit smaller for fuel.. when teeing into two different plates do the jet sizes split in half or do you use a 50 shot size in each for a hundred shot or do you take the hundred shot size and split it in half?
