Spell Hinderance?

[Gompers]

Someone please inform me what I'm doing wrong here?

Armor Use..........................| 210 110

casting with 3 ranks of fluidity:

You gesture.
[Spell Hindrance for an imflass augmented breastplate is 36% with current Armor Use skill, d100= 20]
Your armor prevents the spell from working correctly.
Cast Roundtime 3 Seconds.

According to Krakii, 110 is what is needed...I understand that I'll never completely train it off, but is there something off here?

Thanks

Are you wearing leg greaves or a helm?
