Can you devs please give us the table of llama increase on effects of communitty plazas?

i had 6 llamas and they only gave me 1 exp points per second (the same that 1 llama assigned to plaza), and with duplicate effect of llamas card i had only 1.52 exp per second on 6 llamas. So could you give me the excel table for this? i mean the matematics on how community plaza works.
And please add how much time takes to build walls, buildings, creating units. All this shown on IU.

table of how much less % time takes to build if i assign two villagers, 3 villagers and so on.
