Hey cool script. Just so I am using this correctly.

When I increase the armor use for full leather the only value that changes is the 'New RT Added:' which goes to 0 with 2 armor use. Is this the value I am supposed to use for AP as well or is there no possible reduction in AP for full leather?

For double leather 'New RT Added:' drops at 6 armor use. While the AP doesn't change until 56 armor use which I would probably never train up to for a spell caster using double leather.
