RCE - Marketing influence calculations

Two part question about calculations for reporting on Opportunities.

(1) Based on this setting, how does RCE calculate the following metrics:

• Marketing influenced
• (MT) before Opportunity Created
• (MT) before Opportunity Closed
• (FT) before Opportunity Created
• (FT) before Opportunity Closed

Please note, for the attribution settings of RCE, it's set to "implicit: all contacts regardless of role".

(2) Is there a way to report on Marketing Originated Bookings? If so, how is that calculated in Marketo?
