Sometimes, you don't necessarily want to factor the Account Value of a visitor into your decision making. The predefined "Visitor SmartList" takes several factors into account, one of which is Account Value, and so this could skew your data if you're actively trying to ignore it.
There is another SmartList you can use called "Visitor Priorities".
This list will show you the biggest priorities for your visitors, much like the "Visitor SmartList", only this list does not take Account Value into account.
Alternatively, you can use the "Advanced" tab to tweak it yourself for any report. Go to "Account filters", then "Account Value" and then select "Ignore".
