Pip,
Question for you: Can you find any numbers that tell us more about the Teuton's team bonus of "Units resist conversion"?
I'm guessing it works like Faith. With Faith we know that it means units take 50% longer to be converted. How much longer on average does it take for a Teuton unit to be converted?

"Based on ES’s description, there are three special categories, each which confers 50% resistance to conversion, each of which is cumulative. These are Light Cavalry (and Scout) units, Units with Faith, or Units in a team game with a Teutonic Ally"
Since each by itself confers 50% bonus, the "p" value for converting a unit with one of these bonuses drops from 0.33 to 0.165. If the unit has two such bonuses (for example, a light cavalry unit with faith), the p value is cut in half again, to 0.0825. Finally, if the unit has all three bonuses, the p value is one-eighth the size of a basic unit’s, shrinking to 0.04125.
Prob = 1 - [(1-p)^(m*s)]
So it just works like converting scouts.
