Why do I have 54 AP to distribute?

Attention Points: 0/54

I thought that number would always be a multiple of 10.

From chapelhillne's Guide to the New HD 3.0 release post, here is the excerpt on AP reductions I contributed:

ATTENTION POINTS REDUCTIONS:
When a player signs, that teams attention points will be reduced based on the number of Opening Allocation of Attention points still available divided by the # of openings.

This means if you have 6 or less openings at the start, then you will lose 20 AP each time a recruit signs (The AP already assigned is reduced evenly among the allocated players based on their percentage of the available allocated AP).

If you have more than 6 openings, then you will lose less than 20 (ex. 8 openings but 140 AP, with first signing will lose 120/8 or 15 AP leaving you with 125 AP with 7 openings still).

Gotcha! Thanks!
