There are several aspects to the questions. Temp is one , food demand (fish metabolism) is another and water quality (DO + weather , wind etc)is a third. In addition local adaptation of the BG population is a factor - all are not the same wrt temp profile.

Most likely if the fish are eating well things are ok. Fish will usually tell you what to do. Its the usually that concerns us all as the time to go from ok to uh-oh can be quick. BG max metabolism is good into the high 80s in most cases. You also have to consider your BG population. If its a new pond the young BG will have a faster growth rate and food demand. DO's at 5 ppm is ok. Most do not have that type of data. If in doubt then you should cut back if you have a high feed rate and limited water.
