This may be so and a good deduction. Unfortunately I have not tested this so I can't post a comment. I was laying all between $3 and $30 and was positive although very erratic. I am now taking lessons in excel to be able to test this myself. The answer may be in laying $10 plus. I ran it on maidens only which produced a dismal result so culling the maidens may be worth the effort. I also ran it on the trots and although the results were very good they need to be rerun because some of the results were out of kilter with reality. Time has been an issue and thanks to stuggots for helping me to run these results.
