Maybe it's a well known micromanagement trick, but it's new for me
When there's one turn left until you get a research advance, bring up domestic advisor and move research slider left as far as it can go with research time left staying 1 turn - at later stages, it can give you a turn's worth of very high income (like jumping from 200 to 700+). Of course, don't forget to move it back after you get the advance, hehe.
