Healing Touch Formula

[Kekasi 0]

I have been trying to adjust Luna Unit Frames to add in an "expected heal" from hots.

To do this, I've been using RetroWoW to test all ranks of spells, but I have run into issues.

 

My current understanding of healing is the following formula:

(Heal Amount) + (Bonus Healing)*(Level Modifier)*(Cast Time Modifier)
If Spell Level is under 20:
    Level Modifier = (1 - (20 - (Spell Level))*0.0375)
Else:
    Level Modifier = 1

If Cast Time is under 3.5s:
    Cast Time Modifier = (Cast Time)/3.5
Else:
    Cast Time Modifier = 1 

After testing, I found that Healing Touch (Rank 10) has been gaining twice what it should be from Bonus Healing on Gear.

 

Can anyone tell me what I'm missing? Or is it just a server mod to RetroWoW?
