deciphering dmarc reports

I have setup DMARC w/ policy=none & 10%.  I receive DMARC reports & open in Firefox.  Report file names will have google (email provider), yahoo.com, iphmx.com, etc in the file name.  Each report has who emailed the report, a source IP address & under my domain name headings all results pass.  My domain is compliant.  My expectation is that all emails with be delivered, even if the recipient domain has policy for SPF, DKIM, and DMARC
How can I use these reports to ascertain how many emails my domain receives that fail SPF, DKIM check?  Or is there a better way.

David,
A great explanation.  I will change my DNS entry for separating into 2 reports.  
One more question-when I change policy to reject - where does the rejected email go?  To my spam folder? is it deleted at the SMTP server never to be seen by the recipient?  am I at the mercy of each email provider and how they setup their servers?

OpenDMARC can handle DMARC messages for you   ( http://www.trusteddomain.org/opendmarc/ ) and collect them into a database.
You can use a viewer to view the reporting: https://github.com/techsneeze/opendmarc-dashboard
