Hybrid 1-3 second prediction mod

I received the latest version today. Almost everything works perfectly, but there is an elusive error in calculations somewhere. I’ve been testing all day to pinpoint the source, and likely will be testing all tomorrow too. It is likely just an error in an equation somewhere. Clearly the majority of coding is done for it (all the difficult parts), but I don’t know how long it will take to make it perfect. I can only guess within a week.
 
Afterwards, a part of it needs to be refined so it’s more foolproof. Because if you use it incorrectly, then you’ll reduce accuracy. This additional part is not essential, but I’d rather help avoid players from making mistakes.
