Here’s the quick and dirty:

Ticket.wasted.all.size  
=\> 1

Ticket.wasted.count  
=\> 10

It looks like the count operation is completely ignoring the :group  
option that the “wasted” named scope is setting. I am pretty sure  
calculations allow grouping, any idea why the :group option is being  
ignored here? Or does anyone know a work around for this?

Thanks for your help.
