If I'm right, you're asking how long after testing and feeding you can shoot, right? Most of us do it all in about 15 min. It's best to keep it in the same time frame so that you know you're giving a shot on a specific number. However, there's DEFINITELY leeway if needed. Do you have a situation where you're going to need to alter the schedule? We can help with that if you'll let us know what your schedule needs to look like.
