When originally developed, was it important to have a lot have one input and one output split? This creates extra splits in the account which may be confusing.

I don't think anyone around now really knows what were the design assumptions. IMO the design and implementation are both rather opaque; it always takes me several hours to figure out what's going on when I need to work on that section of code. I haven't done so for several months, so I'm back to being a bit fuzzy about it. 

I don't think that there's a good conceptual reason to split lots when one does a partial sale, so I suppose it was done to simplify the implementation of something. What that might be would take some study.
