Without going too much into maths, I made tables to compare various SBR models according to rules from Global 40, 1942.2, 1942.2 TRIPLE A with Global rules and many more variations, the simplest way to balance SBR for 1942.2 is to **increase damage from D6 to D6+2.**

Hi everyone,

here is a few datas and summary collected after a lot of calculations and messed up tables, here is a real discovery to help any discussion over benefits and disadvantage of various SBR values. Hope you will find interesting numbers to provides some reasons behind intuitive conclusions on SBRs.

I found a useful analysis tool to compare average results of various SBR combat values and cost per unit:

**Break even point and ratio:**

In Strategic Bombing Raid, it is the number of attacking aircraft unit needed compared to intercepting Fg to get even odds on both sides (+0.00 IPC damage/SBR).

**Break even ratio** is a fraction number of Strategic bomber over a single intercepting fighter to reach an even odds of winning or loosing IPCs in a single air raid compared to the defender odds of inflicting damage. A ratio above 1 means that you need more than only 1 Bomber against 1 intercepting Fighter to reach a profitable threshold in SBR; while a ratio below 1 means that making a raid with at least 1 bomber against 1 Fighter interceptor is always advantageous for the attacker.

**Offensive over defensive cost ratio** for same combat values : it is a useful measure to evaluate the comparative higher cost of a given attack value over the same defensive value.

For instance, **Tank gives a 1.00 offensive/defensive cost ratio** because attack 3 and defense 3 is the same cost at 6 IPCs.

3 air attack over 3 ground defense cost gives Fg A3 C10 vs Tank D3 C6 = **1.67 off/defense IPC ratio**.

4 air attack over 4 air defense cost gives StB A4 C12 vs Fg D4 C10 = **1.20 off/def IPC ratio**.

2 artillery ground attack over 2 Infantry ground defense gives Art A2 C4 vs Inf D2 C3 = **1.33 off/def cost ratio**.

2+2 ground attack over 2+2 ground defense gives Inf+Art A2+A2 C7 vs 2 Inf D2+D2 C6 = **1.17 off/def ratio**.

So, this offense/defense cost ratio for the same value goes from 1 to up to 1.67 in regular combat.

Here is a very comprehensive table of various SBR values from stronger to weaker SBR from attacker POV:
