All right. I just did a test round with no runes or masteries. I cannot yet explain the 540 AP incident listed above, but I did determine that, as Silvoss stated, the AP granted by is only calculated once, but  grants +30% to the AP granted by the ult&mdash;which came from the AP already affected by the Deathcap. The result is that the Deathcap is slightly more effective on Jax than other champions.

Here are some numbers. B is your base AP (before the Deathcap's +30%) and U is the flat amount granted by Grandmaster's Might (25, 45, or 65). I hope this clears things up :D.
 * Ultimate only: 1.2BU
 * Deathcap only: 1.3B
 * Both: 1.56B1.3U
