I'm not an expert, but I can tell you this, it comes from tremendous amounts of testing and data. There are numerous things that they have to take into account and it's more than just a simple explanation. Fuel demand requirements, emulsion packages, circuit timing, carb sizing, engine applications, and about a million other things. Well, maybe not a million, but you get the idea. It takes alot to come up with a combo that works, and even with the best tuners out there, someone else will tweak it and tune it just a little better......
