The current armor settings give the following results:
Ships
All: Bridge, 2x LS, 2x CQ, Aux. Con, 5x Heavy APB, 5x Quantum Engine.
Light: 6K hitpoints, 76 x 75hp light armor + 10x18 structural support.
Heavy: 4K hitpoints, 13 x 300hp heavy armor
Mixed: 5K hitpoints, 7x300hp(H) + 7x200(M) + 7x75(L) + 40x18(SS)
Heavy vs Light:
Heavy wins 5 of 15 battles.
Heavy wins 12 of 20 battles.
Heavy wins 7 of 20 battles. (one light-on-the-run)
Heavy wins 7 of 20 battles. (one tie, one heavy-on-the-run)
Heavy wins about 40%
How? Heavy armor blocks a higher % of damage. Light has a higher chance of losing critical components, such as weapons. With more surviving guns, the heavy can sometimes overcome the 2000 hitpoint difference to take a win.
Heavy vs Mixed
Heavy wins 27 out of 50, with one count of Mixed sucessfully running away.
Light vs Mixed
Mixed wins 23 out of 50, with two counts of Light running away.
7 on 7 fleet action!

I tactical'd one of the heavy-vs-lights, and the results were:
All heavies destroyed.
Light 1: OK.
Light 2: 30% damage. 26 armor, 2 engines lost.
Light 3: Totally Destroyed.
Light 4: 14% damage, 13 armor lost.
Light 5: 60% damage. 51 armor, 5 APBs, 1 Crew quarters lost.
Light 6: Totally Destroyed.
Light 7: 18% damage. 15 armor lost.
Plenty of Collateral damage for everyone
I can't say anything about the quality of the tactics (all on auto), but there could have been a couple rammings by otherwise-disabled heavy ships.
I expect the armor-penetration to rise when the large engines & weapons are included, posibly tipping the balance towards heavier armor, but who knows
