I will throw in my opinion. I never considered myself a helicopter parent but always took interest in what my kids did. Whatever their current interest is I always research into it both to educate myself and as a form of entertainment. When my daughter showed interest and ability in running I read everything I could on the subject and even came to this site and asked questions and gradually developed a philosohy that was particularly influenced by the Jack Farrell articles. Near the beginning of her 8th grade I discussed some of my findings with her to get her feedback.
Our conclusion was to break training into 3 areas: frequency, duration and intensity and to focus on the first two as the intensity portion probably needs more competency than we had. It became as simple as gradually increasing duration and ultimately frequency during the off season and leaving the intensity/speed for the coach during season. I am not saying we had the best middle school coach out there but probably not the worst and my gut says consistency in training is as important as the quality at that age.
Last year in the 10th grade she was a top ten finisher in our state in two events. Would she be running faster now if we had hired a professional coach? Maybe, but she could also be worse off. And reality is that she is not an Alexa or Mary C and probably never will be so if her training isn't perfect it just means she has something left in the tank if she runs in college.
My rambling point is that you are worried about the wrong things. Focus on getting her to want to develop a strong base and everything else will slowly fall into place. If your daughter has a 2:09 inside her but only runs a 2:12 because her coach "sucks", in time things will sort themselves out. If she has a 1:59 ability but is only hitting 2:04 then that is a different matter.
