In other words, for any build that has paladin divine sacrifice, the build gets an extra attack swing every 3 seconds. Given that attack swings are roughly 90 per minute (4.5 swings per 3 seconds) up to around 135 attacks per minute (6.75 swings per 3 seconds), this is a DPS increase of around 15-20%. This means that any build that currently uses divine sacrifice, i.e. has 5 or more levels of paladin, currently has its DPS overrepresented by the DPS calculator by around 15-20%.
P.S. You will note this effect when you try out different tiers of divine sacrifice. Going from none to tier 1 gives a huge DPS boost, while going from tier 1 to tier 2 or tier 2 to tier 3 gives very little increase to the DPS.
