Ive learned two things turkey hunting over the last not quite 10 years.
First, it's hard to call too little and easy to call too much. In my experience, once a gobbler calls back once, you want very limited calling to keep him coming .... Play hard to get.
Second, throw out everything you know if you're in a new area, birds in different areas tend to have different "strategies". In one area they may tend to get really fired up from calling, and in other areas they may be relatively quiet and approach almost silently. I remember hunting one area, and birds would call back like hell at first lit, but never show up, around 10am is when the action would start and birds would come in, but with much less fanfare than the early hours.
