Thank you, this makes the values in the planner consistent.
Then if the planner is right, primary stat and then pure damage affixes (MinMax, LightningD, ArcaneD, HolyD, PoisonD, FireD, ColdD) / Bleed stand to be some of the strongest DPS modifiers in the game. Even there's a hint that these values might be in error -- in some cases, the planner applies the max modifier twice. If it's actually just once and they're worth only half as much, they'll still be almost as strong as the Int affix.
%ED, %Haste, Kings, %criticalDamage should take a back seat and bring a lower DPS gain at high levels if this is right.
Here is another quesion, though. Can the same item gain both the MinMaxDamage affix (physical) and the LightningDamage affix? Although they're different affixes they both are in the same affix "group". If so the chances of a good roll on a rare item improve.
Not exactly sure how elemental damage multiplies, but doubt it's the same way due the fact that those affixes got notably higher values.
They actually didn't, if you examine the diablonut database very closely you can find inconsistencies. Examine other datamines and you'll see all elementaldamage affixes with identical numbers to min/max. diablonut just applies the max modifier twice (I think).
Hand crossbow (grand impellor) 98-196 min damage - 131-261 max damage vs 98-196 min holy damage - 229-457 max holy damage.
You are correct that the upper values for elemental damages seem like they have the min damage added onto max damage. 457-261=196 and 229-131=98. Seems consistent enough to be a bug.
Does the holy elemental damage affix still deal holy damage with let's say fire or physical damage dealing ability? If they you maintain the damage type spread then splitting the type definitely seems like beneficial trait.

If you have Cold damage on your weapon and you're doing a Fire ability, the cold damage becomes fire damage.
If you're using an ability with unspecified element type (physical counts as an element) the cold damage carries over as cold and applies a chill. And benefits from or applies your cold-related passive. It seems like mostly melee abilities are unspecified element. Maybe there will be some exceptions for demon hunter.
Now look at the affix database itself in diablonut:
ColdD rank 14 has a max roll of 134-313.
In the planner, when I'm selecting affixes it says: +(67-134)-(157-313) Cold Damage
After I select the affix it says: (67-134) - (157-313)
