Steve,
I have caught the same trout in a day numerous times. Many times I have had them take the same fly. It all depends on how long it takes the trout to calm down after the fight. Sometimes the trout is feeding as soon as one hour after being landed and occasionally I would venture to say that it might take until the next day. They have to slow their heart rate down. When this happens the fish go right back to eating. About what you can get them on, it all depends on what they are eating or what might grab their attention to draw a strike.
On the Pequest I landed the same trout 4 times in one day. The strange part is that the fight was similar all four times. I could not believe how quickly the trout would go back to feeding.
