The paper is paywalled and I'm cheap so don't have the numbers to hand. But in the abstract sense being statistical could go the other way too - i.e. some might get to 90% before they start their exponential decay.

True, exponential doesn't mean much other than e^n where it's implied that n > 1. Though the decay rate for n=100 is quite different than n=1.1.
