What does hitgroup 8 mean?

[Dying-Ducks]

In the "Weapons" tab one can see a hit group graph, which shows where your hits went.

I noticed that sometimes the table left doesn’t match the graph right, like in this example:

Where 200 Damage were made, but only 173 where displayed in the hitgroup graph. So we miss a hit for 27 damage.

After a little search in the .json of that demo I could find, that hitgroup 1 refers to the head, 2 to the Chest and so on until 7 refers to the right leg.
And I figured out that the missing hit was on the "hitgroup 8". So every hit in that group 8 will show up on the left side, but not on the right.

I wonder what "hitgroup 8" even means and why it don't show up in the right grahic that results in not matching data.
I checked the demo on that example and it was a hit to the upper body.

And when we at the topic codes:
Whats up with end_reason?
Bomb explosion is 1, bomb defusion is 7. Whats with 2-6?
Elimination CT is 8 and Elimination T is 9, but time running out is 12.
I never saw any round with 10 or 11.

Hitgroup 8 is the neck, it will be added in the next version.
