Remainder to control child unit count

[Dwane Diblie]

I was wondering if there was a way to use exclusion groops and remainders to control the count of a child unit.
rule I am trying to emulate is:
Unit size is 10 to 30 modles in increments of 10. Exactly half of them must be upgraded to different models. You may have upto 2 of unit A, upto 2 of unit B and the rest myst be Unit C. These limits are irespective of the actual size. So a unit of 10 would can have 2A, 2B and 1C while a unit of 30 can have 2A, 2B and 11C.

If I did it manualy then I could just leave the 3 Units as Effective but this dose not auto fill the compulsery leftovers of the half unit.

Wow, this sounds complex. So to summarise:

The unit can be either 10, 20 or 30 models total.

5, 10 or 15 of these must me upgraded in some way. 2 can be unit A, 2 can be unit B, and the other 1-11 must be unit C.

I think the best way to model this would be a three-level method:

Main (parent unit) - 10, 20, 30 models
- sub-unit - Unit C - 5-15 models (size restricted using a SizeLimit script on an option), "effective" flag set
-- unit A, child of unit C, 1-2 models if added, "effective" flag set
-- unit B, child of unit C, 1-2 models if added, "effective" flag set

That way units A and B add their counts to unit C, and the total should hopefully be deducted from the parent.

Hope this helps!
