Residential Building upgrades

[mitnick912]

I just notice there are only 5 upgrades for each building

Level 1: gives about ~ 52 pop, ~40 experience, and some amount of gold

Level 2: gives about ~ 104 pop, ~40 experience, and some amount of gold

Level 3: gives about ~ 313 pop, ~40 experience, and some amount of gold

Level 4: gives about ~ 752 pop, ~40 experience, and some amount of gold

Level 5: gives about ~ 1836 pop, ~40 experience, and some amount of gold

Is that correct ? I need to calculate the amount of building needed to build in order to reach the target pop
