Weapon and Target DP and PoH. Making sense of numbers

Why am I able to destroy a target with weapon hits which DP adds up to less than the target DP?
When trying to allocate weapons to targets I was looking at the DP on the weapon and targets.
Specifically I needed to destroy a Hardened Submarine Pen (#109) with some AGM-158B JASSM (#11).
After running the strike a couple times I noticed both missing often as well as destroying with fewer than expected missiles.
First, I was noticing lots of misses, so decided to run the strike 20 times in a row to get statistics.
The pen is 20m long and 2m wide.
Ok, so as an aside observations, that is pretty obviously too small, without asking if this is internal or external dimensions. I'm not aware of any 6ft wide military submarines.
The AGM has a CEP of 2m (6.56ft)
I ran 20 strikes of 4 missiles each (75 total missiles) with results: Malfunction 8.0%, Miss 50.7%.
Looking at the target dimensions and doing some geometry, the CEP was actually confirmed to make sense. Since it was long and narrow, we could estimate that the misses are only on one axis, and with target radius 1m and CEP radius 2 meters, 1/4 should hit, but with only one axis, double that so.. we get 50% which is confirmed by the statistics. (Not exactly accurate due to circle distribution applied over a rectangle, but close enough for the purposes)
Additionally, at the same time, I was able to strike a radar installation with the same missile, which had a 12 x 12 meter dimension and it was hit 100 percent of the 20 strikes, with 1 malfunction (95% reliability), again confirming stats.
On to ""Land PoH / Reliability" which for the AGM is 95%. I can only conclude that it is really just reliability, meaning it will malfunction 5% of the time, which at 8% seems close enough.
But it made me wonder if it really is just that, and how this figure applies to other weapons and how it compares to PoK for say, Air to Air missiles?
Damage Points.
Out of 4 missile salvos I usually got 2 to hit. When 3 managed to hit, the target was destroyed.
The target has DP of 1200, and the missiles 207. The logs under Damage just state Armor Penetrated without the DP math. This is obviously relevant to assigning correct weapons as salvos to other land targets .
Why is the target being destroyed with only a combined 621 DP strike? Half of it's DP.
