Thing is, Hull Damage Resistance doesn't work like Shield Damage Reduction.

On one of my guys, his base DR is 27.0%.

Following info from STOwiki:
http://sto.gamepedia.com/Skill:_Starship_Threat_Control
http://sto.gamepedia.com/Skill:_Starship_Hull_Plating
http://sto.gamepedia.com/Damage_resistance

Can easily see how he got to the 27.0%...

Threat Control 3: +5.4 DRR
Hull Plating 6: +12.6 DRR
Accolades: +2.0 DRR
Neut Mk XI: +17.5 DRR
+37.5 DRM...DR=(3*(0.25-(75/(150+DRM))^2))...27.0% DR

APO3 adds +35.5 DRM...our expected new DR would be: 41.06%
It displays 41.1%

AtS1 adds +16.4 DRM...popping that with the APO3 up, would expect 45.556% - which I'd have rounded to 45.6% but the system rounds to 45.5%.

The buffs are adding DRM/DRR - they're not percentages like the shield stuff. The buffs being added don't calculate like SDR does. It's not a case of calculating the DR from the 35.5 DRM and then working through the shield formula. It's just adding the DRR to the DRM and then calculating the new DR.

We know from what Hawk said, that the Disrupt 10% is resisted by the DR. So with that 27% guy, his DR would drop to 19.7%.

DR=(3*(0.25-(75/(150+DRM))^2))
.197 = (3*(0.25-(75/(150+DRM))^2))
0.06566666666666666666666666666667 = (0.25-(75/(150+DRM))^2)
(75/(150+DRM))^2 = 0.18433333333333333333333333333333
75/(150+DRM) = 0.42934057964899303626287485420243
174.68649262391217569465975080569 = 150 + DRM
24.686492623912175694659750805694 = DRM

+35.5 from APO3, would result in a DR of ~36.8%

That's if the APO3 was applied after the Disrupt was applied to the base.

41.06%, ~35.2%% would be what it would be if it were applied to the base + APO3.

So a case of figuring that it doing the recalc after buffs were applied (wore off) being more likely, but just wanting to make sure.

But the other part was regarding other debuffs...which gets a little complicated, eh?

APB/APD apply a -DRR modifier. So does the Mega Torp.

So for the most part, do those just plug into the overall DRM calc to determine DR and then the Disrupt proc is applied as a final mod - being recalculated as all of that changes?

Doesn't matter if the DRM goes negative...

If we look at the formula: NDR = ODR - (10 - (ODR * 0.1) ex: 40 - (10 - (40 * 0.1) = 34%

So going back to the guy from above. 27 - (10 - (27 * 0.1) = 19.7%

But let's apply a -47.1 DRR debuff from shooting at somebody sporting APD3.

37.5 + (-47.1) = -9.6 DRM = -10.6% DR
-10.6 - (10 - (-10.6 * 0.1) = -21.66% DR

Say we apply that 100 damage...
100 * 1.106 = 110.6
100 * 1.2166 = 121.66

The Disrupt proc is still adding 10% damage.

So again, just making sure that the Disrupt proc was a final modifier...

((BaseDRM + (+BuffsDRR) + (-BuffsDRR))converted to DR - Disrupt = new DR

That it's recalculated like that each time a buff/debuff is added/wears off...
