Lead by Example - The leader improves the Aim, Will and Hack of soldiers within Command Range by half the difference between soldier and leader.

Source: Inside the mod LW_OfficerPack/Localization/XComGame.int

My question is does this bonus work only if the leader has a higher stat than my soldier, or does it work only based on the difference?:

Specialist: 140 Hack
Leader: 20 Hack
(140-20)/2 = 60.
Specialist (140 + 60) = 200 Hack?
