30 cm Nebelwerfer Defensive Fire Glitch?

[Konigstiger88]

I was comparing the defensive fire abilities of various artillery units; for accurate comparisons i always use the Berlin Scenario as the test ground with the hotseat setting. I use a British Para unit to attack a german heavy infantry in a city backed up by X artillery (X=whatever artillery piece i'm comparing). I always make sure the units are in the same locations and have the same entrenchment level. I will list the various casualty predictions of the british unit attacking the entrenched german unit with artillery cover:
30 cm nebelwerfer: -4 to 0
Wurfrahman/21cm nebelwerfer: -9 to 0
Hummel: -7 to 2
Brummbar: -7 to 2
10.5 cm soft artillery: -7 to 2
Panzerwerfer: -8 to 1

As you can see the 30 cm Nebelwerfer is the lowest, but why is this? The other soft nebelwerfer's are better, as are all other forms of artillery. I examined the stats in the equipment files and see no reason for this.
Anyone have any idea why this is?

As a first thought, I would have expected this to be due to the higher caliber and therefore a lower rate of fire... however, I can't get this confirmed when looking at the equipment file...

Have you tried checking the combat details table for an explanation? No offense meant but easiest to check the obvious first, you did remember to use Chess (no random) mode too, correct?

[PeteMitchell]

Sounds like a good idea, if needed you could even share screenshots of these combat details tables/windows, i.e. when pressing the key "L" after the combat/attack...

I did some quick testing and found the 30cm to have the most devastating prediction as expected.

I ran several tests on this, i lowered the soft attack score on the 30 cm nebelwerfer by 1 until it was at 26. At 26 the casualty prediction changed from -4 to 0, to -9 to 0. I had the british unit attack with both versions of the Nebelwerfer defensive firing and compared the combat details. The details are as follows (I can't screen shot on my computer).
The normal 30 cm Nebelwerfer: Miss 10%, Suppress 56%, kill 34%, 3 killed, 6 suppressed.
The lowered to 26 soft dmg Nebelwerfer: Miss 10%, Suppress 53%, kill 37%, 4 killed, 6 suppressed.
Of note (and probably explaining this effect) is that for the normal nebelwerfer defensive fire breaks up the attack, preventing further casualties. The lowered dmg nebelwerfer does not breakup the attack (inflicting 1 less casualty) and the British unit attacks the entrenched german infantry taking more casualties. So the prediction is lower because the artillery attack breaks up the attack before the normal attack.
