Has anyone done any analysis on whether the actual drop rate of keys matches Blizzard's published rates (for MP levels less than 10)? I am asking because I do keyruns at MP5, and I have not been getting anything even close to a 50% drop rate. I am averaging about one drop every 5 runs. In addition, I have had multiple losing streaks of 13 and 14 runs in a row without a key. Now, I realize that a random 50% drop cycle can yield long losing streaks, but still - the probability of a 14 run losing streak in a series with a 50% chance is quite low. Having that occur multiple times seems to strain the probabilities. Also, while you might expect long losing streaks, in a truly random cycle you would also expect the counter-balancing long winning streaks - say, getting 10 keys in 15 runs. So, has anyone looked at this? Or do people only do keyruns at MP10, where the probabilities don't enter into it? Thanks for any input.
