Also I believe the equation you are using is wrong.

"Hit: 4 (1d6 + 1) piercing damage"

I think the 4 is actually the average damage, rather than a multiplier.
That is, 1d6 averages out to 3, add 1 for an average damage of 4 per successful attack.

It makes very little sense otherwise...
As taken as a multiplier, then a Skeleton with CR rating of 1/4 and has 13 (2d8 + 4) hit points...
and a sword slash from one does 5 (1d6 + 2)...

I agree with you on this and have edited my post accordingly. As for the rest of what you said, let's see what [@The Mighty Hero] thinks about it.
