Back in the day, the base pop growth percentage was 4% per tick, or a multiple of 1.04

for bonuses, the modified popgrowth multiples were :
(-30%): 1.028; (-20%): 1.032; (-10%): 1.036; (nil): 1.04; (10%): 1.044; (20%): 1.048; (30%): 1.052; (40%): 1.056; (50%): 1.06

Why is my pop growing at slightly over 5% per tick here at sor? (a multiple of approx. 1.05014).  I have no pop growth bonus. It is not related to a different race I had before SOR; I kept the race since joining the family.

Was the formula base changed? I had a quick look in questions/announcements but didn't find anything.

Also, it seems my LQs house 650 pop rather than 500 as I remember? I didn't see this in the guide though, which still says 500.
