Under what condition will subtask estimates be rolled up to their parent tasks? Is this available on for the "Original Estimate" field?

[R Lockhart]

There has been lots of discussion and opinion around this, but I'm looking for a simple answer: under what condition will subtask estimates be rolled up to their parent tasks? Is this available only for the "Original Estimate" field? We are using a field called Development Estimate, and have it defined as our Estimation Statistic in our board configuration. If I leave the estimate on a task empty, but estimate the subtasks, the Development Estimate in the parent task remains blank. I am hoping to find a way to show estimate roll-ups.

In short I would say no, your custom field won't roll up.
