Matchlock / Rifle damage upgrades

[Artorias]

Hello everyone, in Avatar conquest, does the damage upgrade for matchlock units actually increase the killing power of the unit? I don't see any difference. You can also put two damage upgrades in donderbuss cavalry, even heavy gunners, but I assume it's useless. In FOTS imperial guard cav and revolver cav also have the option to increase damage.

Does anybody know if it's worth the skill point?

I thought I heard somewhere on the forum that every point increases the chance a bullet will penetrate through a man by 10%, hitting the man behind him. Of course with heavy gunners and donderbuss cavalry it would be hard to tell the improvement, and usually something else would be a better choice.
