Question about Auto-attack odds

[Dibbun]

When you do a string of single attacks, the attacks are calculated individually (obviously)

When you do an auto-attack, is each attack still individually calculated, or is there a collective calculation for the entire result?

About the dice

19. How does the dice work?

We have a series of 50,000 true random numbers from Random.org. Each time the game engine processes an assault or auto-assault, it select a random spot in the series to read from using a pseudo-random computer function. Each time the game engine rolls the dice, the next number is read in sequence from the series (e.g. in a 3v1 attack 4 numbers are read sequentially). The series of 50,000 true random numbers from Random.org is replaced every hour. As of June 2010 we process 1,000,000 assaults per day.
20. Seriously, how could I possibly lose X troops while assaulting a region that only had Y? Are the dice broken?

The dice on this site are randomized by Random.org and by being an active member of Conquer Club you experience a very large number of dice rolls so it is natural to occasionally get your ass kicked. It is human nature to remember the losses more than the wins.
21. Why is the amount of data on my dice stats more/less than I expect?

First of all, we only started recording dice stats as of May 2011 so battles before that date are not included in the data. We only store the last 100 battles per player over all opponents as "recent" stats, so if you filter recent stats by opponent over 25 battles there there might not be 25 "recent" battles with that specific opponent and less data will appear than expected. Also, auto-assaults are considered a single battle so recent stats may contain more data than expected if there were auto-assaults.
22. How is luck calculated on my dice stats?

For dice distribution, luck is the actual average roll over the expected average roll (i.e. 3.5). Luck can range from -100% for an average roll of 1.00 to +100% for an average roll of 6.00.

For battle outcomes, luck is based on the ratio of kills over losses. For each type of battle (e.g. 3 vs 2, 1 vs 1, etc.) we know the expected ratio of kills over losses for both assault and defend based on the table below.
3 vs 2 3 vs 1 2 vs 2 2 vs 1 1 vs 2 1 vs 1
Assault 54.0% 66.0% 39.0% 57.9% 25.5% 41.7%
Defend 46.0% 34.0% 61.0% 42.1% 74.5% 58.3%

Luck is how many percentage points the actual ratio is above or below the expected ratio. To calculate total luck (i.e. assault + defend) we take a weighted average of ratios based on the amounts of assult battles and defend battles.

Red and green are used to emphasize negative and positive luck, respectively.
