Question about Additional Potential

[IImaplers]

Roughly guessing, I've got about 175% int and about 550-ish magic attack. I recently went on an additional pot run. One time one of my equips got something like 2% all stat. I decided (maybe it was unwise to) to recube and got 10 magic attack. The 10 magic attack gave me about 2k more max range than the 2% all-stat did, which I found peculiar. It led me to consider that the stat %s or just an increase of a stat works like it does in azwan, only adding the the base and not the totals including the potential, while the magic attack includes the totals after potential. I could be gravely wrong though since I wasn't very careful testing it out (maybe one of my skills ran out and I failed to notice). I'm going on a whim. Would I be wrong or right?

560/550>177/175

What joe said, 1% stat seems to hover around 2 attk, you simply got a lot of attack
