Question AC Value Formula

I'm a bit confused on the formula for AC. Here is an example of an issue I'm experiencing on my server with a spell that has the following values:

effect_base_value1 = 30
max1 = 55
formula1 = 101:Effect Base + Level / 2

My character is level 49. According to the formula, this means:
30+49/2= 54.5 AC

What I actually see in game is an AC boost of +15

I'm obviously misunderstanding the formula. Can anyone explain why I am seeing a value of +15 AC in game, when it should be a value of +54.5 AC in game (based on the above formula)?
Yes, I remembered to re-export my client files from the server side and overwrite them on the client side.

P.S: I suck at math

Your math is fine. Spell AC is weird. If you take off an item worth 40+ AC the change is huge, but with a spell it's much smaller.

If you look at #mystats, under mitigation AC, there is a field for "spell."

On my level 60 GM char using crappy GM armor, my mitigation AC is 360. If I take off my 40 AC breastplate it drops to 306. When I cast Resolution it goes up to 373 (up from 360). However, "spell" goes from 0 to 55 (reflecting the full value of Resolution).

Someone better with the actual AC formula might can chime in, though.

Boom, exactly. Shit is complicated lol.

We still have pre-AC split too; which on live separated Mitigation and Avoidance AC into different values.
