Adding Dimensions changes

[GoogleCodeExporter]

Name of affected component: Core Reporting API

Issue summary:
When adding dimensions into the query, the numbers are changing. For example, 
when I run with a single dimension for transactionRevenue, I will see a number. 
When I add a dimension for visits, visits will show up but then the 
transactionRevenue will turn to zero. 

Steps to reproduce issue:
1. Run a query with dimension Transaction revenue only. 
2. Run a query with dimension Page Visits only.
3. Run a query with both dimensions. 

Expected output:
We expect by adding dimensions that we will see additional values. For example, 
if transactionRevenue was 15 when I ran that dimension only and visits was 25 
when I ran that dimension only, then if I run both, I should see 15 and 25. 

Actual results:
What do you actually see after performing the above steps?

Notes:
Provide any additional information which might be useful here. Feel free to
attach screenshots or sample code which demonstrates the issue being
described.

Can you provide the fully request and response?
Is sampling an issue? Are there any changes in the filters or segments you are 
using?

I updated sampling to use higher_precision and still having the issue. 

I've attached an image from the explorer of doing the same query with / without 
the addition of adContent and keyword. 

There are no changes in the filters or segments.

I also found that if the date range is 1 day, it matches. However, the longer 
the date range, the more off it is.

According to the attached documents it appears that the results are sampled:

To avoid sampling you can always request smaller date ranges, and combine data 
from multiple requests.
