The screenshot is not from a PDF. It is from the DMI reports.
If you open up any DMI report and edit it you will see the following.
If you click on the "learn dimension and metric definitions" link (https://aa.bb.cc.dd/dmiDvHelp?app=CVENT&dv=ClientView) a window listing all of the dimension and metric definitions will open. My "screen shot" is a copy and paste of each of those 4 metrics.
Thanks and God bless,
