Help explain combat results.

I am playing as the Allies.
Before Japan's move the New Zealand 4th/5th Tac group is at 14/20 strength and at 91% effectiveness. They are set for automatic naval interdiction.

During Japan's turn they try some naval interdiction. They are also involved when Japan's 1st Air Division (air superiority group) gets involved.

After the fight I look at the 4th/5th Tac group and it is at 13/20 strength and at 76% effectiveness. Looking at the combat results however, it look like they lost 7 strength points. Below is the two combat results. What happened?

My best guess is that naval air strike losses include the air superiority losses, for a total loss of 4. You then got 3 replacements (max 20% per turn, or 5 for airgroups). We’re you bottlenecked by replacement production?

I thought about the reinforcement thing as well, but it took forever to build it up to the 14. I was getting 1 or 2 strength a turn and did not change my production.

Even then the numbers don't add up. It started at 14. It lost, if I am reading it right 7. Even if it got 5 back that should place it at 12 not 13.

I am saying that the air to air combat losses are included in the total losses under "naval air strike." That way you lost four and gained three.

You may be correct and I thought about that as well.

Another possibility I discovered after reading the manual for about the 4th time is that losses can be converted to effectiveness losses. Could it be that we are being shown losses then some of the losses are converted to effectiveness losses?
