Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

How evidence-direct are the estimates?

Let's translate the numbers into implied doubling periods:
10000 BC - 400 BC: 2055 years;
400 BC - 0: 556 years;
0 - 200: 7056 years;
200 - 600: minus 1311 years ("decay");
600 - 1000: 1416 years;
1000 - 1200: 303 years;
1200 - 1340: 972 years;
1340 - 1400: minus 253 years;
1400 - 1500: 336 years;
1500 - 1600: 306 years;
1600 - 1700: 427 years;
1700 - 1750: 276 years;
1750 - 1800: 163 years;
1800 - 1850: 132 years;
1850 - 1900: 126 years;
1900 - 1950: 80 years;
1950 - 2000: 38 years.

That is a wild variation. And the industrial "singularity" is staggering, isn't it?

For comparison, the implied biblical doubling period is about 190 years.
