[ANSWERED] Meaning of the eight PID Types?

[Eco-Mono]

OK, so I understand how each of the eight types only shows up in certain situations, but I'm curious as to what distinguishes them from each other internally - how you can tell them apart. Like, for instance, Type1/Normal DS is "A-B-C-D", and Type5 is "B-A-D-E". But, what makes a given PID/IV combination a Type1 and not a Type2 or Type3 or etc.? In fact, what do those sequences of letters mean in the first place?

Thanks for any help you can give

Edit: So I did a little more digging and finally got my answers. Turns out the explanation isn't as simple as I had hoped; the letters actually have to do with the order in which numbers spat out by the PRNG are used in generating the PID and IVs. (This is also apparently why eggs don't have PID/IV matching problems - they are generated at separate times so any number of RNG hits might have occured in between.) Well, anyway, found my answer so there's no need to keep this thread going.
