Calling all Paladins: Regarding Holy Charge Damage

[Doctor Omega]

Okay, I do not normally post threads like this, but I am having a really hard time wrapping my head around this.
According to the skills themselves, this is what we have:

1. Flame Charge - Base damage = 140% (200% with Elemental Void/Elementalism)
2. Blizzard Charge - Base damage = 140% (200% with Elemental Void/Elementalism)
3. Lightning Charge - Base damage = 250% (310% with Elemental Void/Elementalism)
4. Divine Charge - Base damage = 405% (Not affected by Elemental Void/Elementalism)

My question is simple. On paper, divine charge still has the highest damage percentage, even when the other three are boosted by Elementalism. If this is the case, why in the world does my Divine Charge have the lowest damage output? When all elemental charges are maxed out at 5 and I have the Blast buff active, I do around 800k-1m per line with Blizzard, Flame, and Lightning charges. However, when I use the Divine Charge, the damage is lower than all of those, at around 700k per line. If this skill really has 405% damage, why in the world are the other three out-damaging it? Even with Elementalism active, the first three charges still have less damage than the Divine Charge. Am I missing something?

Elemental Void (now known as Elemental Force) increases damage on all charges except Holy by 210% as a passive effect. I'm not totally sure where you got 60% from.

Oh good lord. I searched for the newest paladin skill list I could find because I don't have my laptop with me. That must've been an old one I was looking at. Welp, this is a useless thread now. Mods can delete it if desired.
