Nice thread you have here!
There are many things I don't understand of your strategies:
- What are the lbs for?
- What are your 5 civics?
- How do you keep your economy going?
1)
lbs? Where have you read of them? Sorry but I don't know the meaning

2 and 3)
Pyramyds are mandatory; when I complete the oracle and achieve CS, I switch to
rapresentation
burocracy
caste system
the reason is obvious
The rex has to be microbalanced with research; after cs you must have first calendar, then currency (you have to build the mausoleum of mausolus asap).
If you do well you can go for the fist golden age at about 300 BC. Before I think is useless, better to do it when you r building market in the capital, parthenon, hanging gardens and so on. Delay your second golden age (reserching music, obvioulsy) when you are near banking , at about 100 BC, so you can switch to merchantilism and organized religion. Even better, if you have already built the swedagon paya, you can go for
rapresentation
burocracy
caste system
merchantilism
free religion
all before Christ.
These civics will change only after economy with free market. NEVER adopt ambientalism, it will cost you at least about 8000 gpt if you have spread well your corporation.
Once you've discoverer biology and medicine and corporations, your game will be cycle switch beetwen rapresentation and universal suffrage, BETTER if you have the redemptor.
Another (obvious) tip: found the sid sushi in the capital, and add asap the wall street, this is the reason why it's better to maintain the burocracy, even if you have 250 cities

In fact your cottages were built only int the rex city to sustain the initial economy. After that period your gold will be golden age, conquering cities, pillaging some neighbor, and specialist economy. You will be able to buy all your executives, markets, banks, harbors, settlers, courthouses in the initial stage of your sushi expansion when your research is cruising at 0%.
Sometimes switch to rapresentation to have some tech in 3/4 turns.
In the final stage you will be able to counter the

emancipation penalty with your future techs
Sorry for the worst english ever seen on this forum
