Trauma Again

I got docked for tissue trauma again today. I thought I was doing better but apparently I'm not. This is very frustrating. Every time I get docked for Tissue trauma the instructor gives me a reason of what they think I did but thier answers are never consistent. SOme think I'm applying too much pressure, some say it might be my instrument selection, some say that I am probably not adapting to the tooth enough. This is so frustrating to me. I wish I could just have one of them watch me the whole time to help me figure it out. How am I supposed to correct the problem if I'm not positive what is causing it.
