For example, instead of estimating a particular task will take 5 days, you might estimate it as 5–6 days if you’re fairly confident you know how much work is required, or 1–10 days if you do not really know what needs to be done. Both ranges average at 5.5 days, but the first represents a more predictable delivery.

There was a bug report in 2014:

Date: Tue, 16 Dec 2014 11:45:21 -0500
Message-ID: <CAG2CFAaaFUyM5MJRfYxJ=kjnqmS=ub54Rx3NVtsgDMcyHQ-zsQ@mail.gmail.com>
To: emacs-orgmode@gnu.org
Subject: [O] Bug: est+ not working,
 or perhaps under-documented [8.2.10 (release_8.2.10 @
 c:/Users/yhluc00/emacs/share/emacs/24.4/lisp/org/)]

With a reply and a patch by Nicolas:

Subject: Re: [O] Bug: est+ not working,

X-BeenThere: emacs-orgmode@gnu.org
X-Mailman-Version: 2.1.14

Proper syntax is simply

  :Effort: 4-12

But this gives:
Invalid duration format: "4-12“

Here is the patch:
