The Math for the Tech Levels

[marshman]

It seems it is based on # of provinces with larger empires not being abble to advance as quickly. has anyone been able to figure out precisely how the # of provinces impacts your requirement for advancing tech levels? In other games at some point --I think 80 provinces the impact went away. Is there a similar limit here?

it would be less than 80 provinces probably because that is like one third the map, but i dont know the exact modifier.

patchnotes said it was changed from number of provinces to total population
im guessing because by only taking over large pop provinces u could boost your research alot before
