CRM Analytics - Elegant Comparator

CRM Analytics - Elegant Comparator

Anyone noticed a wierd thing on the Elegant Comparator on CRM...

Compare Among - Time Period - Last 6 Weeks... only 5 weeks show
Compare Among - Time Period - Last 5 Weeks... only 4 weeks show
Compare Among - Time Period - Last 4 Weeks... only 3 weeks show
Compare Among - Time Period - Last 3 Weeks... correctly, 3 weeks show
Compare Among - Time Period - Last 2 Weeks... correctly, 2 weeks show

Anyone else spotted this? 

It would be such a better comparator if it allowed you to include the current week too.... having one comparator for the history and a separate one for this week looks horrible.  

Thoughts?
