Instead of a single charge that refills Gryphon's missiles to max capacity, Missile Autoforge starts with two charges that refill standard amount of ammo used by the weapon. For example, Harpoon rack has three missiles, and Gryphon starts with at least six (because of built-in Expanded Missile Racks). With the proposed change, using the system once would add three missiles to the rack (or up to maximum), and the system can be used twice.
The net effect is doubling an unskilled Gryphon's missile capacity (or x4 normal capacity), but less than what Gryphon with either or both Tier 5 combat skills with the current method. With this change, a Gryphon with Systems Expertise or Missile Specialization would have x5 capacity (instead of x6 capacity), and one with both would have x6 capacity (instead of x9 capacity).
