New Kharkov '43 Campaign

[Indragnir]

Please help me out here with the readme of the new scenario, on page 2 it mentions:
"Quality Fire Modifier is set to 2. That means any B unit will get a +20% bonus (plus their +10% bonus base) and A quality units +40% bonus (plus their +20% base). C quality units have no effect and D quality units have a -40% (plus their -10% base).
Since all Russian formations (except for the 2nd Guards Tank Corps) are now C quality, the negative side of the rule won't cause any trouble... until Russian gets enough fatigue or become Disrupted.(Same for Germans have they usually have better Quality)

If any unit is D quality (Fatigue, Low Ammo, Low Fuel, Disruption, Isolation) that unit will suffer a -50% thus reducing their fire capacity to half (others modifiers like Disruption or Low Ammo will worsen the situation.)
If your units drop to D, either rest them or regroup them like they did historically or you will have (likely) only 25% of your fire capacity vs up to +50% firing modifier if you're attacking an A quality unit."

I think the math is wrong, the manual notes the Bonus for A/B units as times the Quality Fire Modifier, so if it's set at 2 it would give a bonus of +40%/+20% for A/B units. That this would go on top of the base value, and by that give would give +60%/+30%, is afaik wrong.

Also for D units the malus isn't -50% but just -10% because it doesn't matter what is set for the Quality Fire Modifier as that value only modifies A/B units.

From the manual:
There is a Quality Fire Modifier Parameter Data value, which is by default equal to one, that applies to fire modifiers for A and B units below.
• If the Quality of the firing unit is A, then +20% times the Quality Fire Modifier value applies.
• If the Quality of the firing unit is B, then +10% times the Quality Fire Modifier value applies.
• If the Quality of the firing unit is C, then no firing modifier applies.
• If the Quality of the firing unit is D, then a –20% modifier applies.
• If the Quality of the firing unit is E, then a –40% modifier applies.
• If the Quality of the firing unit is F, then a –60% modifier applies

Seems contradictory. Maybe a test is needed to figure out how it works properly.
However I think you're right on the +60%/+30%. To achieve 50% bonus QFM 2.5 would be needed.

PS: New notes and Kharkov 43 v2 for 1.04 patch is almost ready for you test.

Did a quick test. Bigduke66 is right, despite of what manual states, QFM only works on A/B units.

Is that a bug or working as intended?
If it's not a bug then all Russian infantry should go back to D and QFM should go to 2.5
