change the number of posts required to change level.

Unfortunately, I didn't quite understand the explanation, but I still can't figure out how it shifted by one level. If before, from 750 to 1000 experience points, it was level 8 (for example, I had an **Archmage**). Now, from 750 to 1000 experience points, it's level 7 (a regular **Mage**). I can't understand it: confused. Sincerely.
