[CentOS] vdo statustics on Dedup?

I've started to use "vdo" instead of zfs in Centos 7. I hope this is
a wise decision. However, I'm a bit mystified in decoding the
I'd like to figure out how well deduplication is working. One
measure would be to find two numbers:
L = How many bocks are in use as reported to tools like df
P = How many actual blocks are in use.
Then a value such as L/P, which can never be less than 1, would be
interesting. If I have typically four copies of everything, I'd
expect to see L/P close to 4.00.
What two numbers, in the "vdostats" do this if any?
