Can someone please explain Zone of Control points, Evasion points, and Zone of Control generated by the enemy and how they relate to each other. I have searched the Manual and find no mention. I know it has to do with movement restrictions but how is it calculated and what does it all mean? Thanks.

Its explained on page 29 of the manual.
Have you looked there?
Or what you are asking is a more in depth explanation?

Yes of course I saw that. I don't see the term "Zone of Control" or "Zone of Control Points" mention there. It mentions evasion values. Is that evasion points that is mentioned in the game tool tip? The Tool tip does not use the term "Patrol Value". I know a patrol value is assignet to each element. If I have a stack of 18 elements (DIV) each with a patrol value and an evasion value, how does each of those factor into Zone of Control calculations ie. zone of control points and evasion points?
I know I should just play the game and forget it but I have just always wondered what was under the hood and how it works.

Hi gbs!

The ZOC should work like this:

Evasion Value:
The unit with the lowest evasion value will determine the evasion value of the unit stack.
Bad weather will give you some bonus to the evasion value.
Additionally you will get some bonus/penalty for a small/big stack.

Patrol/Zone of Control value:
The patrol values of all elements are added.
A fort gives a big bonus to the patrol value (depends from fort level and military control).
Military control over a region gives you also some bonus to the patrol value.

As it can't said better I quote Pocus here (hope he don't mind):
"The Rule
You can’t enter in a land region, if the patrol value (of the region you are in) divided by the Evasion value (of your group) is greater than the military control (yours) of the region you want to move.

The minimum control value needed is adjusted by substracting 2x the Evasion value of the group. This is made so that a small ZOC is not sufficient to prevent you from entering a region where you have no control at all."

This is not clear to me. Subtracting 2x the evasion value from what? Can you give an example?

Thanks, Chris

After calculating the glueing effect of the enemy ZOC, say you find that you need at least 25% of military control (YOUR) in a region to enter it. Then you substract twice your evasion to this value (which is low for infantry and high for cavalry).

Merci so :-

You cannot enter a land region if the (enemy patrol value/friendly evasion value) > (your military control + (2 * friendly evasion value)) in the region you want to move into.

Chris

yes

I think this should read (your militaty control - (2 * friendly evasion value))

Am I correct?

If for example military control was zero it should be + to give you some chance to enter.

That's exactly how I read it, and Pocus confirmed that's the way the formula works. BUt it doesn't seem to actually work that way in the game.

In this thread from last week - http://www.ageod-forum.com/showthread.php?t=12748 - it shows these values for Lee's stack:

Your Force can penetrate areas which are at least 88% military controlled.
Evasion points of your force: 1.
Zone Control points generated by your possessions: 898.
Zone of Control points generated by the enemy: 147.

According to the formula, Lee should only be able to move into an area where he has 145% military control, which makes no sense:

Military Control required to move into region = P/E - 2*E, where P is the enemy ZOC value and E is Lee's Evasion Value. That's 147/1 - 2*1 = 145 MC.

Lee's 898 ZOC should be irrelevant to the calculation.

I can't find any way to make these numbers work within the context of the formula. The only way it works with the given enemy ZOC and the given MC threshold is if Lee's evasion value is really 1.61. But that does not round down to 1, unless the game rounds down all fractions to the nearest whole number.

The way I see it, any time you have an evasion value of 1, which most large stacks do, the formula will yield a required MC value of over 100% if the enemy force has at least 102 ZOC points. That's obviously not correct, as it would prevent you from moving eveninto areas you control 100%!

Is there some other hidden modifier that comes into play when dealing with large stacks? Or am I using the wrong numbers in the calculation?

Maybe the ZOC effect reaches a maximum level at 90% Military Control, and the the 2X Evasion adjustment with 1 evasion point brings the required MC down to 88%. That would make sense, and it would mean that 88% is the most MC that would ever be required for you to move into a region.

Clever Major Tom... indeed!

The control is bounded to 90%. And then you remove from that 2x your patrol... This allow you to retreat to your rear lines.

Thanks for confirming, Pocus.

Zone of Control seems to be one of the least understood mechanisms in the game, based on what I've read on the message board. I finally think I'm starting to figure it out. And now that I've penetrated the mystery, I think I really like the system. It's very elegant.
