The statement about post project reviews being a prime source of estimating data is accurate. After a project is completed, conducting a post-project review allows project teams to evaluate what was planned versus what was actually achieved. This retrospective examination can yield valuable insights into how long tasks actually took, potential pitfalls, and factors that may not have been considered during the initial estimation phase. This information can then be used to improve future project estimates by making them more informed and grounded in actual historical data.

In contrast, the other statements present limitations or misconceptions about estimation practices. For instance, the notion that an estimated cost must be a specific percentage, such as 10 percent, to be useful is overly restrictive and does not consider the context or accuracy of the estimate. Similarly, stating that if task durations cannot be estimated within a certain percentage there's no value in developing a schedule undermines the importance of planning and managing risk within projects. Lastly, the idea that project managers should always add a specific percentage to duration estimates to account for optimism is a generalization that may not apply in all cases, and could potentially lead to inaccurate timeframes if not carefully justified.
