Not right.
For Normal speed and 1.0.1.511:
Worker = 70
LS - i don't know what is it
Cannon = 185
Public School = 300
Military Base = 500
Stock Exchange = 500
Brandenberg Gate = 750
City production will be different while you produce units/buildings/wonders, but if it's average 100 you can get 585 hammers overflow this way:
100 after Worker,
185 after Cannon (LS - don't need)
285 after Public School
385 after Military Base
485 after Stock Exchange
585 after Brandenberg Gate
If you change Cannon to Theatre=200, for example, you will get 600 hammers overflow at the end. Or you need ~104 hammers per turn while you are building last 4 components.
Overflow should be less then max(current building cost, city production per turn).
Overflow is never more than the hammer count of what you build. That's why you go from small builds to large.
