Elsenet, a colleague recently asked about the likelihood of Twilight: 2000 4e PCs making it to various numbers of lifepath terms before the war kicks off. Assuming a RAW implementation of a 1d8 roll under the number of terms taken thus far, the distribution looks something like this:

… so your “average” 4e PC will four terms of character development before the war breaks out. Anything above 6 terms is a significant outlier (and probably doesn’t have great attributes from all those aging rolls).
(I think I got this right, but my math is not guaranteed. It’s been a minute since I did anything with probabilities, and I somehow managed to get a master’s degree without ever taking a college statistics course.)
