I've seen this debated a number of times but never seen a final resolution on it. I searched but came up empty handed, so if it has been and I missed it I apologise for brigning it up again , but anyway...

When you've got one turn to gain an adavance, generally only a certain amount of the research generated on that turn is need for the advance. What happens to the remaining research generated that turn? Does it get held over for your next discovery or does it go to waste?

I think that it go to waste. In the last turn I always put the slide to the minimum percentage that gives me the advance in one turn. Make much gold that way.:)

I know it goes to waste. Hence this is why most people put their sliders down at 1 turn to go :)

Sometimes I start checking at 3 turns, often at 2 turns. You can push the slider down one or two notches at 2 or 3 turns and not lose any time either. Then again, sometimes I forget completely and it gets wasted.

It doesn't matter if you start looking at 5 turns to go or 1. If you move the slider with 5 turns and save 10 gpt you'll get the same savings at 1 turn. Instead of 5 turns at 10 gpt less you'll get 1 turn of 50 gpt less. In the end if you really, REALLY need that extra cash now then go ahead and do it. Otherwise just wait until science hits 1 turn left.

Like all habits you need to practice this. Plenty of times I would click for a new turn and realize I hadn't reset my science slider. After a while you'll stop missing the opportunity.
