Congratulations! The 400,000 point club puts you in some pretty elite company! How did those zone markers I told you about (for points) match up for you? I think you and I are at about the same level of skill on this track. So I'll be looking forward to your updates!
Also, when do you typically have your first flawed zone? I have made it to Zone 91 without hitting anything, but typically I hit the wall for the first time around Zone 70 in a moment of carelessness.
