So that just about fits in for the 10-days in a season. Allowing for weather and delays we maybe want to be looking at 2-season shifts at the Esk Valley.

+Approximately [[nine sixteenths|http://www.representingchildhood.pitt.edu/medieval_child.htm]] of live births survived to the age of 10 and in 1250 they had a life expectancy of about 30 more years at that point. Population was growing at an anazing rate (England was in danger of a Malthusian collapse by the time the Black Death hit a century later) so babies were being live-born at about twice the replacement rate - 1 for every 15 people over the age of 10 each year. The covenant pays well (positive LCM) so infant mortality will be below average and mostly below the age of 5 (we can ignore kids below that age. Lets say 25% total infant mortality - actually it's going to work out slightly less than that when we convert to covenant population points), so lets call that 1 for every 20 over 10. Each Year. So a full fifth of the covenant population is going to be between 5 and 10 at any point. Better keep them away from the magi! Actually it isn't because the LCM factor applies to the adults too - meaning they'll live longer. As an aside approxinately 1% of pregnancies are twins (but twin births tend to be bad news in medieval times).
