Tables that are highlighted with the letter "F" are APIs/Reports that do not support incremental data extract. When a replication job for these tables are executed, the entire contents of the source table are replicated. 

For example, if a table named "Profile" has 100 rows in it, and the table is set to replicate every hour, you can expect 2400 rows to count towards your billing for 1 day.

Your usage is based on the number of rows extracted by Daton. Loading modes Upsert, Append, or Truncate and load only determine how the data is loaded, not what what data is extracted from source and therefore have no change to billing. These options are provided to help you manage the volume of data in your data warehouse.
