Just out of curiosity, what does the distribution look like on the move intervals? If your last 100 "big ones" were 100 years apart (90 times) and 10,000 years

Just out of curiosity, what does the distribution look like on the move intervals? If your last 100 "big ones" were 100 years apart (90 times) and 10,000 years apart (10 times), your median interval is 100 years and your average interval 1000, but if you're at 2000 years you might reasonably expect another 8,000 years before the next one...
