The Dink Network

I was checking out some stuff that I never really thought about in the past, things such as the variable limit. Back then I wasn't much of a programmer, just a kid trying to learn how to do some Dink stuff. But now that I've finished my computer science education I have the urge to do everything RIGHT from the beginning

So, onto my question...

I've been eliminating all left over variables in Legend's Tale that weren't disposed of correctly, but I've run into a dubious situation... When I use var_used() I get the current amount of variables in use, correct? So, I've been running around checking if it increases beyond the normal amount all over the map, during and after events, etc... So far, I only encountered a few of them and fixed them. But, then I checked again using the Save Game Editor of Justice and, well, there were a lot of other variables in there, often present in large amounts of the same variable... So, now onto the REAL QUESTION: Which one counts toward the variable limit, var_used() or those that can be seen in the save game editor?

Hopefully someone here has the experience or knowledge to help me out
