What kind of unit sizes are we talking about here? Will you go all up to 253 (or 100+3 officers for those who like it EDU-style) for some units or do you have some upper limit lower than that?
It's not really a question of "staying true" to RC or not. rusnmat states clearly that his mod is inspired by RC but also based on his own research - which means that Prince of Judah:s submod (subsubmod?) is that as well. The different EDU:s discussed should be judged by how well they work out in the game, not just how closely they follow which RC guidelines, since that is not the sole point of all of them.The differences between what rusnmat did and what I did were that I used the latest guidelines from PB and that I knew what I was doing - both in terms of staying true to RC instead of coming up with a lot of half-baked, gut-feeling, "this is too different from Vanilla M2 so it makes me uncomfortable" ideas and in terms of having created RR/RC-style EDU and EDB before.
Prince of Judah is doing a lot of guesswork as well, taking a point off here, adding another one there, hmm, this unit killed the enemy unit "too easily", so let's change its animation, reduce its armour... The beauty of RC is that it's a system, with rules. It is those rules that provide consistency.
And as for "guesswork"; what's wrong with that as long as you are open with what you do? You have to guess a lot before you are done with a consistent and balanced stat system.
