Hello all,
I am in not a math expert, so I hope I can get help here.
Here is what I am trying to understand:

Each development cycle, the team delivers points by working a certain amount of hours.
I can calculate 2 ratios, which are "inverted" of each other
Why isn't it the case?
Thanks you for your help,
Charles
