IPD and Damage upgrades yield lower results

Hi. Great game!

I've been trying to upgrade the weapon on my Marauder character when I noticed that the numbers I was getting for things like Damage Scaling and Added Phys Damage were very low for the iLevel on the item. I'm new and may not understand how this stuff works, but according to this page I should be getting much higher results when I add damage to the weapon:

This Abyssal Axe is Level 55, but only yields Glinting 2-5 Phys damage when I use an Alt orb on it (hopefully you can see images on Steam; not sure how to upload screenshots to your forum):

Same with IPD. I get Wicked 65-84% (iLevel 23), but if the Item Affix website is correct, the range should be 110%-134%:

I verified the install with Steam, and it found no problems with my game.

Maybe I'm just missing something?

The item level only affects the highest mod available and doesn't change the lowest. At the highest item level, all mods are available. They are weighted so the lowest ones spawn more often than the highest ones.
Try rerolling it hundreds of times and you'll eventually get the highest mod available for the item.

Thanks much for the information. That's disappointing. Guess I'll keep trying. :)
