Total is actually hugely important; it's the only way to get deduped counts in Adobe Analytics. As soon as you do a Unique Visitor (aka Unique User) count of any kind, you quickly discover that in many cases, UU cannot be and should not summed; the only deduped count is that little "total". Yes, it's misleading, it's undocumented, it's calcs are not clearly defined on the screen, even why it appears sometimes and not others, all true... and all good reasons to fix this, initially for total, then...

With today's calculated metric builder, you can use functions to create weighted metrics for any event captured. Additionally, we have included some metric templates in the builder for weighted bounce rate.

I think this is basically the same suggestion as in http://ideas.omniture.com/t5/Adobe-Idea-Exchange-for-Omniture/Tagcontainer-Management-Tagm anager/idi-p/7301, but definitely a needed feature in TagManager. /Henning
