Does that mean if 10 planes vs 5 planes, both sides will lose the same amount each 15 min at the beginning?
No. A 10 plane stack will do more damage than a 5 plane stack. But 2 stacks of 5 planes of the same type will do considerably more damage than 1 stack of 10 planes when an enemy timer ticks. For example, the efficiency of a 10 plane stack might only be say 70% X the attack or defense points.
I don't have a 10 interceptor stack to give an actual value.
For Interceptor lv. 1,
10 interceptors x 5 Defense value X .70 efficiency x 100% condition = 35 defense value per enemy tick
NOTE: With 1 stack, you lose an interceptor every time the interceptor hit points gets to a multiple of 20. So if your units aren't at 100%, it might not take many hit points to lose a plane. Ideally after each round, you would estimate your risk of losing a plane. if it looks like you will lose a plane, you might want to send an interceptor back to base.
5 interceptors x 2 stacks x 5 Defense value x 1.00 efficiency x 100% condition = 50 defense value per enemy tick
NOTE: With 2 stacks, you can take as much as 40 points damage at 100% condition before you lose a plane since the stack has to lose interceptor hit points before you lose a plane.
Over time, you are averaging about 42% more damage which means the enemy stack will lose planes quicker and you will lose fewer planes. This would be true for other levels too since only the defensive value would change.

Put another way, you have a higher chance of inflicting more damage with 2 stacks of 5 interceptors defending than with a single stack of 10 interceptors defending. The game is very much one of estimating the chances of winning battles and estimating risks.
Thank you Lawrence. You are helpful.
