To make this a little clearer for you: It's not so much waiting for 24 hours, as it is waiting until you see proof that the yeast have moved out of the lag phase and have begun converting things into alcohol. This is called "proof". I feed as soon as I see "proof that fermentation has begun. So in theory this could be in just a few hours. Or as long as a few days. I read quite often where people are concerned because their lag phase has lasted for several days. I would be concerned if lag took more than 8 hours. I feel it it takes longer than that you might have underpitched your amount of yeast. 2 grams a gallon is a good rule of thumb up until 1120. Higher than that would benefit from 3 grams a gallon or even more in some instances. ( I don't make single gallons anymore, or even 3 gallons for that matter) but if I were to make a gallon I still always used to use the entire packet of 5 grams anyway. I buy it in much larger amounts. I wouldn't try to store a partial packet of yeast. It's only a couple dollars anyway.
Most nebee's would benefit from using more yeast as is. Rehydration is the first place people start to make mistakes. It's very important to get your yeast off to a good start so learn how.
You won't find a single scientific article saying to feed past the 1/3 (first third) sugar break. Only lack of faith would urge someone to feed past this point. With Fermaid O you would be OK if you feed past the first break, but if you start out right there is no reason to if you are using dry wine yeast.
