Gurps Space. Low TL world population.

[pro100kostya]

In Gurps Space on p. 92 there is "At TL4 or below, a homeworld’s population is likely to be within 50% of its carrying capacity. Select a population as needed, or roll 2d+3, divide by 10 (retaining fractions), and multiply by the carrying capacity to get the world’s population."

Is it just me or these 2 sentences are contradicted?

2d+3 is 10 on the average. We divide it by 10 and get 1. So on the average we get population equal to carrying capacity. But the 1st sentence states it should be within 50% of the carrying capacity.

"Within 50% of its carrying capacity" I believe means that it is between 50% and 150% of its carrying capacity. (2d+3)/10 gives a range between 0.5 and 1.5, so it works just fine.

Looks like you are right.
