Once the data are on your screen, you can manipulate them for easier viewing. The first step is to click and drag the year column heading into the bar area above the table. This will organize the data by year. You can then repeat the procedure with the "infosource_type" column heading, creating a second level hierarchy in the organization so you can focus only on the latest submission values. Now you can view data across Parties for a single year.

As a reviewer, you should also note the information contained in the documentation boxes in the CRF tables themselves. These boxes frequently contain explanations and supporting information for how estimates were derived as well as references to where more detailed information can be found in the NIR.
