I believe that I've found the answer. It's directly under Culture in the Game Concepts section of the civilopedia.
You're correct. It doubles every 1,000 years.
There's also the tourist attraction attribute to wonders that adds additional commerce. The amount starts after year 1000 at +2. After 500 more years it reaches +4. It will eventually get to +14 at the year 2501. This can all be found under Tourist Attraction in the civilopedia.
I hope that this helps your understanding![]()
Thank you. It does.
