Gravity Racer ramp – lines

Q:  The ramp we were given for practice does not have marks or lines on it. I would like to add them so the students have the best practice experience possible. The ramp at the training meeting also had no lines so I have not seen what the actual competition ramp would look like.  I know the lines are supposed to be in 10cm increments. Do they go all the way across the ramp? Do they start exactly 10 cm from the top? Would it be possible to send a picture of a competition ramp so we can add lines to our ramp to be as close to that as possible?
A:  A PDF with some pictures of the competition ramp has been posted on the Gravity Racer page.
