Oh, agreed, it's not a surprise that this happens.  Where the uncertainty
seems to lie is in the mathematical modeling of cracking -- that is,
[some of] the models don't seem to fully account for the accelerative
effects.  I think this in turn partially explains why reality keeps turning
out to be worse than forecast.
