No Turtle, your analogy is not mine. I am referring specifically to the oil pan. To use your analogy it would be an updated video driver, not an entirely new operating system. My point is many seem to condemn the pursuit of zero defects as bad. I think you have two entirely different arguments in your post above. One being a substitute and the other a refinement. Mine is not a 7.3, 6.0, 6.7 etc debate. The problem is many of these treads get so perverted you cannot follow them when the haters (not you) attempt to derail a discussion.
