Weighted averages by definition does take into account EVERYTHING. That's why I'm very puzzled when you make statements like these. My average rounds to kill takes into account rounds 1 to infinity. Your chance to kill by round X only takes into account rounds 1 to X.
No, weighted averages take into account what you've decided to measure and how you've decided to weight it. If I take the weighted average of the volume of a cat from tip to tail, I haven't said much about the dietary requirements of the cat, although some information towards that may be gleaned. Being able to take a weighted average does not, at all, mean you've successfully measured everything. This is reification -- you've done math and confused the concrete outcome of the math as applying to your assumptions. Nothing in stats will correct your assumptions -- tools will gleefully let you lie to yourself with the absolute certainty of a math equation. Don't confuse "I did math!" for "I did it right!"

For example, if you look at your round two, the information contained is that the creature wasn't killed in round one and here are the odds it is killed in round two. In mine, all of the information is present -- both the odds it was killed in round one and the odds it was killed in round two. These are answering different questions, so missing information isn't necessarily a bad thing, but you need to really look at what you've decided to measure to see if it suits your assumptions. Doing math doesn't fix faulty assumptions.

And, so far, I'm unclear as to what your assumptions are -- you seem to think that because you've shown something that this means that another thing is less valid (the overkill fallacy, as you've termed it). This is like taking the weighted average of a the volume of a cat and declaring that you know it's dietary needs, though -- these things may correlate on some level, but they aren't causative in the way you've presented them. You haven't shown how your weighted average says anything at all about overkill.

Found the error. I needed to account for half rounds.

You keep saying things like that but it's simply not true. Calculating a weighted average for chance to kill on round (X) results in a value that is the number of rounds to kill. There's no misinterpreting what that means. It means exactly what I'm claiming it means.

For example, if you look at your round two, the information contained is that the creature wasn't killed in round one and here are the odds it is killed in round two. In mine, all of the information is present -- both the odds it was killed in round one and the odds it was killed in round two.

For comparing 2 different characters chances to kill. The rounds to kill an enemy is a much better metric than presenting someone with 2 probability distributions.

Sigh. You can't declare your answer to be the right one by fiat. Explain why you think this is so. Following my own advice, it's because the assumptions are slightly different. I'm assuming at least one more enemy, so the case on a round where there was 1 previous hit and two hits on that round carries the second hit into the new target, This reduces the overall average because I'm not stopping at one enemy so that the difference in distributions matters -- by assuming at least one more bad guy, I've removed the artifact of the different distributions of hit probability. I've applied mine to the continuum, not just the one specific situation. I've also accounted for that third wheel of a third hit.

To go back to an earlier point, have you investigated the region where target hp is from 9-12 in your construction? PC2 is ahead of the game, there. This means that bigger stick isn't always faster to the kill. What do you think this says (not snark)?

I didn't. I showed my calculations. There was an error in them though. I needed .5 rounds accounted for. That was throwing it off. Now as expected the 1 attack characters and the 2 attack character are killing 5-8 hp enemies at the same rate.

So basically disregard the premise of this post as the math around it was incorrect (stupid .5 rounds).

But I think it's given me some ideas on how to calculate the effect of overkill damage.

No, this is the weighted average of the "chance to kill on round X", not the weighted average of the" number of rounds to kill". Your metric shows that a kill is most likely to occur sometime in round 2, because that's the weighted average of the chance to kill across all rounds (assuming the later rounds are essentially zero). You can't shift what you've measured into something new with a weighted average, so this isn't the weighted average of the "number of rounds to kill."

There is a different between 'chance to kill ON round X' and 'chance to kill BY round X'. You show the former, not the latter. Your average is the average chance to kill ON round X. My method shows chance to kill BY round X. Different things.

This is, admittedly, a narrow point, but if you're going to lamblast me for lack of understanding, I feel it's a vital one.

For comparing 2 different characters chances to kill. The rounds to kill an enemy is a much better metric than presenting someone with 2 probability distributions.
Again, not quite what you're showing. So, the argument that yours is more useful without being able to say what mine is useful for shows that your assuming instead of discussing. You show kill ON, I show kill BY. Both seem pretty useful information.

Example: As PC1, what are the odds I will kill the monster ON round 3? Your method is the proper one. Those odds are ~10%.

Also as PC1, what are the odds I will kill the monster BY round 3? My method answers. Those odds are ~94%.

Different things. You don't show which round the monster will be killed on or by, and, honestly, neither do I. We both answer different questions. Playing the game is the only way to answer which round the monster will be killed on.a Don't fall into the trap of reification and assuming that your math says more than it does.

According to what I've put up, it shows that certain DPRs are equivalent against a particular foe. PC1, for instance, has the same kill ratio for 8 damage as for 5 damage against the 5hp foe. Thus, overkill doesn't hasten kill rate. This will be very specific to the foe, though.

8. @Ovinomancer, by the way I can account for multiple enemies etc in my formulas. The only thing I can't implement yet is variable damage dice.

My formula is surisingly easy to use. Simply list rounds out. Find first round enemy can be killed and then copy paste my formula in every cell.

9. You guys don't see the irony here, do you? The posts in this thread absolutely - and without doubt - prove that overkill is highly devastating. The lenth of posts in this thread was enough to kill any joy in topic five pages ago.
