Fully resolved. Looks likely to be correct, although its possible Dispense Decoy is a little less, and a small contribution comes from an unlockable (e.g. Commando). My current data suggests this isn't the case though. If you have a reasonable level of Dispense Decoy, your skills and profession level would be useful to confirm that.
