Sure...video review is very helpful. A great tool to get better.
If you can't get someone to video...try a mirror. Many officials are surprised by what they see...i.e. fist not punching a hole through the roof, stance looks off-balance, frown on face when reporting, etc.
BTW...I see you are from Onatario, Oregon...I have a friend that is the assistant coach at your local community college.
Do you officiate college ball/H.S. ball in that area?
