It's one thing to make the most of your opportunities to sharpen your skills but it's another to roll the dice while thinking happy thoughts.
I have a number of corners on my commute that I would love to take faster or to use for sharpening turning technique, including several on what is supposed to be a private road, but most do not offer enough sight distance to make wicking it up any more than an act of unwarranted optimism.
You appear to not have a grasp of what I said or I am misunderstanding what you've said.
It is not sloppy and it is not rolling the dice. It is developing skills in changing position by practicing a bit when the conditions (corners/surfaces)
are known or have a good line of sight. Learn how tighten your line and you now have a tool to deal with a surprise decreasing radius turn should you suddenly realize it rounding a blind turn. It is practicing both mentally and physically how to change up a line mid-corner, not pushing the envelope. It is developing both knowledge and faith in the handling of the equipment - especially tires. It is incredible how tenacious the grip of tires can be - far beyond the skill of most riders. I have never had a tire break loose due to leaning on any pavement.
My line changing practice is not haphazard. It is not go zig zag at random, nor is it wobble about like a clown. Fact of the matter speed has nothing to do with it. I do not see where conclusions like that were drawn.
