For some reason, up until now, I did not realize I had an error in my calculator involving the flat damage added. I only found out recently when I was testing for the new characters (who did +7 damage).
Before, I was adding this damage before Specials. So when calculating damage using Specials that multiply the damage, such as Damage x 150%, it would give a wrong results.
This update fixes it.
The link is still the same, it seems, and the link to it is somewhere on the right area of the page where I have a bunch of post links.
