Excellent suggestion. You can learn plenty from watching the grown ups and how they approach things. And most of the guys will go out of their way to help a new shooter as long as you aren't a dick.
Two quick hints on that though.
Don't start asking questions when he's on standby and is getting his shit together to shoot the stage. Or even worse when he's walking to the line.
Don't tell the dude who just crushed you on the stage how he's wrong when he gives you advice because Mcmillan Rosebush and Instructor 32 degrees on you tube said you should do it differently
Oh and Matt Hopkins is right
On your walk through
"Exit out the back of the stage!!"
