Whoever wrote this for this entire wiki used the cheapest item (Amplifying Tome in this case for AP, 435g for 20 AP, 21.75g per AP) as the reference point, while treating the other, "better" items giving premiums.. just because people use Needlessly Large Rod as the reference point (due to lowest gold/AP), doesn't mean anyone's wrong, it's just a different method of calculation.

For example: Needlessly Large Rod, for 1600g you get 80 AP (not including Archmage masteries and whatever else)

For 1600g, you should get 1600g / 21.75g/AP = 73.6 AP

So with this, you're paying for 73.6 AP, and getting 6.4 AP as a premium for saving up for this item.
