Reduce spell cost not working properly?

My jewelry with reduces spell cost by 20 only reduce spell costs by 14 each.

Because you also have 30% cost reduction (LA, class/racial passives, seducer set).

% cost reduction is applied after flat cost reduction.

It's effect is negated by passive cost reductions.

Does the math work? Yes

Does it make common sense? Maybe, maybe not.

Will you please explain how flat reduce cost is mitigated by % reduce cost in this instance?

Magicka cost=(base cost - flat reduction)*(1-passive reduction)
