As you pointed out, we need to improve it for a better user experience.
Thank you for your valuable feedback to improve the documentation :)

Wasn't sure if I should submit a new issue for this, but as far as I understand, the line printed after each task is showing (in parentheses) the run time of the previous task, which is confusing and not very useful.
