Well that's a very good explanation Andy, it sheds some light to things that otherwise could only be known by guessing or experience.
Maybe some of the developers could kindly document these "under the hood" things like the way Tiller's PzC/MC documentation describes its game mechanics.
For now, the only way to get those thing is by reading posts from Don or Andy (yes, the GG has some good coverage on the mechanic but not comprehensive I think).
Some things have startled me like the way tanks are more vulnerable from direct AT fire when traversing downhill (as the top armor is quite visible), etc.
