You are very obviously taking the assumed compound average of population increase for the recent and the early time periods and applying it to the earlier time periods when he actual rates were substantially less than 1 percent or negative percentages for centuries at a time. The population rates of the most most recent centuries and millenia are far higher than those of the earliest periods, so they are not representative of the early periods. Using the average of the entire period grossly distorts the final product of those calculations In other words, it is an elementary school level failure in basic mathematics.
Again, I think you have me confused with the original poster, since you don’t seem to be responding to anything I actually posted about.
