Quite a coincidence on the choice of 100,000/settlement.
It’s like a middle school kid with a homework assignment read, and then tried unsuccessfully to plagiarize my 2014 blog: Unsuccessfully because assigned a linear (rather than exponential) rate of construction “Assuming a construction rate of 500 settlements per year”.
But I suppose, if one were desperate, one could imagine that hidden in the “thought process” were the necessary exponential calculations that simply disagreed in a substantial way with my own, and then calculated an annual average over the exponentiation regime.
