I&#x27;m interested to know if anyone here has used this over an extended period of time. Does it work for you? Have you become better at estimating? Have you lowered your defect rate? Have you increased your pace?<p>I&#x27;m skeptical that something this prescriptive could be effective, but it&#x27;d be great if there was evidence (anecdotal or a study) that shows this is effective.
