I'm great, bro!
I thought your idea was really good, and your request couldn't be simpler.
I just needed to include a parameter to select a variable and point the rest of the old variable's code (lvlPoints) to the variable of your choice.
I added a file to the plugin's file list called Kadajah_LvlPoints(variable).zip; this file already has the version adjusted to use the variable as you mentioned.
In other words, this version of the JS file is ready to be used as you suggested.
Thanks for your comment,
