Lead Performance Report Values Changing
I'm having some issues figuring out how the lead performance report is supposed to work and why my data is ALWAYS changing.

Main question on this report is why is %won 82.4%? Shouldn't it be 56/126 so that it's 44%?
This is what the setup looks like. But this is going to lead to more questions.

Should be only brining in leads that have been created in the last 90 days right?
Ok so just in case I'm going to add a filter to my smart list.

Now my report looks like this.

All of the data just changed...but realistically that filter shouldn't have done anything since they the setup and smart list is saying just show me leads in the last 90 days. Also why is the %won now 100%?
Ok so now what if I was to just change what things are grouped by, the totals should be the same right?

This is my new grouping. (Still have the 90 day filter on the smart list)

Although the grouping changes, why should the totals be changing?
Basically at the end of the day what I'm trying to figure out is a simple funnel and then compare it by properties such as campaign or sales rep.
