We (think we) managed to figure it out over on the discord channel.

The damage calculation is basically damage dealt = (attack - defense) * ammo penalty where defense = 0.7 * armour + 0.6 * x where 0 =< x =<armour -1

So with the debuff active its damage dealt = (attack - (defense - 23)) * ammo penalty

In other words, its a +23 damage postcap bonus if we're reading everything correctly.
