Big Picture - Original Estimate

[Esteban Halabi]

Hi Everyone, hope you're doing well.

I need a little help understanding what a big picture default field is displaying and I can't find anything in the documentation.

On the Big Picture root view there is a default column called original estimate (tasks) [sum]

I need to know where this field is pulling information from?

Let me explain

Reference epic in a project (1,152h) Original Estimate

Now this is what I see at project level in Big Picture (this is perfect, it matches)

But now back to the root view we have this Original Estimate (tasks) [sum] and this is what I see

Where is that number coming from?

It doesn't match the original estimate, nor the time remaining, nor the subtraction of one vs the other.
