Correct statement.  You forgot one zero.

He will be able to make this more clear once he has read what people
have stated in other responses.

Respectfully, of course, Richard Golodner

Great question!  Let's say between 6Gbps and 8Gbps dirty.

As someone making a living as a DDoS mitigation engineer for the
last 10 years (minus 1 month) I should say your threat model is sort
of unusual.  Potential miscreants today should be assumed to have
much more to show you even on a daily basis.

Is it like you also have something filtering upstream for you, e.g.
flowspec-enabled peers?

AFAIK new threats (SYN+ACK amplification) can't be mitigated over
flowspec and they can reach 40+Gbps easily.
