I'm kind of in the same boat. I've hit 500k one time, but I'm usually between 250-400k. I've never gotten a handle on wild barrels, though I'm getting better. It's usually bad luck on rivets that does me in. If you watch some of the insane point pressing done by the best in the world, you know how hard that is, and how much of a grind it is. That takes a constant level of concentration I will never have. So, I'm concentrating on being a little conservative - not worrying about the score, not worrying about the Bonus timer on non-rivet screens, not taking too many risks. I just have to constantly remind myself - right now, points aren't the goal - finishing the level without dying is the goal. Easier said than done. Good luck.
