Bulbing Great Scientists
The amount of science is the accumulation of the last 8 turns of science you have generated. In my last game I kept all Great Scientists from the 1 I got from the Porcelain Tower to when I wanted to rush to Telecommunications. At the time I bulbed them(3 at that time) I was generating 800 science and it allowed me to steal the CN Tower from China who was several techs ahead of me.
You might argue that creating Academies would be the best approach but I was surrounded by grassland and wanted to focus on growth/culture/science via specialists. sometimes its best to keep your Great Scientists for the opportune moment.
Careful. This is not correct anymore. Amount of beakers for bulbing gets fixed to the amount WHEN the Scientist is born. Saving them for the future will not increase that amount.
Mathematically, you will have to compare the amount of bulbing beakers with the average beaker creation of an academy plus the amplification factors in the city where the academies serve (can take 18 as an average rule of thumb for a well developed Science city, usually the capital), times the number of turns you expect the game to go on (or the tech target for comparison).
