I would love to have the cameras that you mention. My first year I had an instructor ride along, and asked him to monitor how close the right side of my car was to cones. I thought I was right up on them, but he told me I was about 2' away! I think I've shaved it down, but I still don't know for sure.
It doesn't help that the annual Solo School has been held on weekends that my National Guard unit is on duty two year running.
Congrats and good luck on taking it to another level. I agree with you. Keep it GS until you've got everything your car can give you.
