Here's an example of a DV booking I had back in June. Paid F (C &D class) earn 150% miles (based on distance flown) and you get 1/5 of those miles earned as MQDs (shown in each individual segment). Then add the 1.75x status accelerator multiplier for MQDs in FC (shown as the total amount in the box). Not bad seeing as the total cost of the package was $1500 each including hotel and we got $1871 MQD each for the flights.
