This has to be the last time I reply to this....

Rubik, I looked at your spreadsheet example and found a big problem, at least in my Excel, the random number function produces an 'evenly distributed' set of random numbers (it says so in the formula description), so this cannot represent the independent craft events that occur in game. Also at 50% odds either way, like the flip of a coin, it will at times appear as if the average/overall probability is 50% but it does not have to stay that way.

Gidget, sample size is irrelevant. These are independent events, so their population is 1. There is an equation for determining the correct sample size of a population, but it requires the population size, standard deviation, and the z-scores that correspond to the desired confidence interval. You can't do that with independent events, no matter how much data you collect. And we don't need to because the population of an independent event is 1 and we already are given the probability for one action, it is displayed in the craft window.

Bittty, going back to my roulette example (which I have to correct since we have 38 spaces on an American roulette wheel) no matter how many observations you make and calculate the probability from, these are just curious observations. They have no analytical or predictive value. There is no overall or average success rate for a group of independent events since they are in fact independent of each other. The closest we can get would be to ask questions like: What is the probability of hitting number 7 four times in a row? We can easily calculate this by doing (1/38)^4=0.00000048 or less than 5 in a million. Applying this to an Armilo tool situation: What is the probability of no boosts in ten crafts? (9/10)^10=.03486. So even with ten crafts the probability of all failing is still almost 35%, nearly 25% more than your success rate of an individual action. It takes 22 crafts for the chance of failure to fall below the chance of success (9/10)^22=0.0984. But even multiplying the probabilities of independent events is still just an estimation, they are independent and each action is still as probable as its own success rate.

Observations on roulette can have predictive value if the physical object deviates from an ideal object - e.g. it has some slight material deformations that make it more probable for the ball to end on a certain number (or a class of numbers).

Similarly, random number generators used to be quite weak on computers. One may observe behaviour in the hope that a weak one was implemented in game :D

Placio -- You have consistently misunderstood the word "random" and the difference between a priori expectations and observational measurements of events directed by chance.

You seem to have the "gambler's fallacy" locked down, but you are seriously misinterpreting it. I don't know what textbooks or schooling you are taking for your interpretation but either they are wrong or your interpretation of them is. I made my living for 40+ years interpreting results that were based on the measurement of random impacts of photons on a receptor. I know the statistics.

Bittty - That simplifies matters greatly.

Placio - The reason I say large sample sizes are better is because we don't know the actual numbers behind the curtain. In the event of a roulette wheel or coin toss, we could get away with a smaller sample size simply because we already know the mechanics; they are 1d38 and 1d2.
When you don't know how the numbers are generated though, it takes a bit more data to figure out. If I rolled 2d10 about thirty times, it's entirely possible that I could roll mostly 7s and not have a single result above 12 and thus mistakenly assume that I'm rolling 2d6, but the more I roll, the more likely is is that I'll get a distribution curve that matches what 2d10 would put out.
You are correct that prior results have no impact on future results, but no matter how many times I flip a coin, I can predict with a high degree of certainty that my next toss will be either Heads or Tails with a 50% chance of either... assuming a perfect coin.

Mjollren - You mean like coin tosses generally being 51/49 affairs due to the fact that coins are not perfectly balanced?

Do not assume that you speak for all just because you are the loudest voice; there are many who disagree that simply have no desire to waste words on you.
The q30 simple writing accessories clearly state they will give 6 skill points bonus. I use them regularly when crafting and have seen these skill boosts: 6,8,10,10, and 9.

The scrolls do NOT work as intended.

Cathach -- what are you talking about? The skill level increase does not show -- it is just applied. All random factors involved in crafting are also applied. Screenies???

Ok, Let me copy the info of q30 Simple Writing Necessities for you: Modifies your Craft skills by 6 point(s) for 10 min and 40 sec.

Somehow, the origional intent seems to have been changed, such that the items of any level can have any value. I gave examples of greater benefits than the occupation level deserved.

These random values, of any level, obviates any need to take risk and accomplish the highest level of an occupation. This idea of "any random benefit" flys in the face of the notion of achievement. I recommend that the indicated values for this occupation be restored.

What do you mean you've *seen* these boosts? As Bittty said, your skill is simply modified behind the scenes. Have you tracked the rate of degrades and concluded it's all over the place?
