Yup think you pretty much nailed it there...
In the 80's when I was active it was very cut thoat I wanted to shoot for the exact reasons you mentioned...because it was fun and I loved the practise and adventure...however the competitive politics ruined it for me and eventally took the fun out of it...
If I had advise for any new shooters to the 3D circuit it would be ...by all means do your best... but overall have fun and enjoy the adventure !!!
