At any rate, I decided to code my own script to replace the stat calculator. Usage is simple - just enter your current (or desired) stats and level, and the script will automatically calculate stat bonuses! However, in addition to Kickkat's calculations, this script will also give you HP and MP, RA monster levels, costs for training to your next level, and the L value needed to determine which size of treasure chest you will receive on the Travel quests. In fact, now you can even do exp calculations - all the stats you need calculated on one easy page!
One bonus of this calculator is that it's completely open, so you can look at the code and see how your bonuses are being calculated. This also means that all you need to do is copy the page source, and you have your very own stat calculator to use locally!
Many thanks to kickkat for stickying a post for this, and thanks to everyone who has given me positive input on this stat calculator so far!
