The easy formula for checking the probability of making this many rolls to attain a TN of 30 is ...
10 ^ ((Current Post Number - 2090)) x log (0.999))
The 0.999 is the probability of rolling something other than a 30, which is 999/1000.
This series of rolls began on Post #2091, so to find out how many posts have been made since this started, subtract 2090 from the current post # and you have an idea of how many rolls have been attempted. A number of posts were 3d6 or some other attempt, and a small number were just text posts, so the number of attempts is an "upper bound".
The Log and 10^ operations are used because many calculators will not perform exponential calculations a large number of times. I don't know why the microprocessor instructions don't use the same mathematical operation I do, but many appear to have a routine to iterate the exponential function, which is computer programming malpractice in my view. At the current count we have ...
10 ^ ((3441 - 2090) x log (0.999)) = 10^ ((1351) x (-0.00043451177)) = 10^ (-0.5870254067) = 0.2588 -or- 25.9% chance of taking this long to roll the Target Number. The 50% mark occurred at post number 2783. The problem is that all the previous rolls now don't matter. We still have to "expect" to take 693 more rolls to hit the TN.
