This is my understanding of the differences between the two mods:
The number of charges also changes after reloading. Reloading the game changes the values to something other than their initially created value, at higher levels this causes a significant decrease in the value of enchanted items.
When enchanting, as your enchantment skills increases and your enchantments become better and stronger, the value of the items you enchant actually decreases.
One of the reasons that I found this new mod interesting is that it takes a very different, almost opposite, approach to addressing the same general bug. STEP already includes Enchantment Reload Fix by egocarib, which isn't compatible with this mod, but is a very well regarded mod. I wanted to at least bring this mod to the attention of others who might know more about this particular issue. I've never done much enchanting, so I'm not really familiar with the bug described, but it looked interesting so I figured I'd make a topic for it. This is a recently released mod that supposedly provides a partial fix to the inaccurate enchantment values.
