My rule of thumb is to look at how many beakers I'd get from bulbing.
-If it's less than 6K, there's enough game left to be played that academies are still a good choice.
-If it's between 6K-10K, turn click GS's until they reach 10K
-10K or more, bulb away.(Which coincidentally is usually about 8-12 turns after all cities have labs.
2 other considerations are:
1.) How the game is progressing. If things are rough and particularly if I'm being DoWed upon when trying to turtle, I may bulb earlier to get Infantry earlier - makes em' behave better. If it's smooth sailing and economy is good, I may start saving earlier.
2.) How many cities I have. The above formula is for 3-4 city tradition, technically add 5% to all values per city over 4.
