Going back to my post above, we have the math for a Tatara with T1 rig.

51 \* 1.04 (Tatara) \* 1.12 (NullSec) = 59.4048

So now let’s look at T2 Athanor in Null…

53 \* 1.02 (Athanor) \* 1.12 (NullSec) = 60.5472

The rig difference has a larger impact than the structure bonuses. Is that what you are trying to confirm?
