Are combat tactic modifiers cumulative?

[Kryndude]

If I'm trying to maximize the chance of firing Massive Longbow Valley tactic, the modifiers are

• 1.5 - Martial 8, Archers 60%

• 1.5 - Martial 12, Archers 50%

• 1.5 - Martial 16, Archers 40%

So for example if my army has 60% or more (or does it have to be less than 60%? how does this work?) archers and my general has 16 or more Martial, do I receive all the above modifiers and gain additional 4.5 tactic weight?

Or do I get one modifier at a time for each tactic?

The exact mechanism isn't really apparent in the wiki text.

They are cumulative. They increase the chance of that tactic firing.

so in above case I get total 4.5 modifier?

No, those each multiply the base weight of 3, giving a total weight to the tactic of 10.125.

FWIW it's better to keep the archer percentage just a bit under 60%, so that your opponents won't roll the "charge on undefended" tactic and switch you over into melee. Here's the easiest/best way I could figure out to maximize longbow volley without having tons of retinues :

One completely bare bones castle holding levy (60 LI, 150 HI, 15 LC), plus one levy from a City with small Barracks and 30% levy bonus (Arsenal, etc) gives you a max of about 158 LI, 150 HI, 130 Pikemen, 52 Archers, and 15 LC.

Throw in two Longbow retinues and you end up with a 1005 man flank that's 15.7% LI, 14.9% HI, 12.9% Pikemen, 55.0% Archers, and 1.5% LC. That's pretty easily attainable in early game, and throws Massive Longbow Volley 69% of the time in skirmish if you put in a M16+ English/Welsh leader.
