Morning Woof43. If you have time (I'll keep an eye on this thread) could you, perhaps give an actual example of how you would do that for tomorrow's race (any tomorrow!!). This is NOT a challenge or anything like that as I'm aware that nothing is INFALLIBLE. Whether it pans out the way it "should" on any individual race is not so important as the long term principle. I'd much appreciate it as you really seem to have a fine grasp of the maths/stats. Thanks
