    Here is a bit of growth rate information found on octopus.com . If you scroll down to O.Briareus, the information is there.


    It basically says they attain 75% of their adult size in the first 17 weeks of their life. The article is not written all that well, and some of the information contained within the text contradicts itself (multiple times), but the basic core information on the species seems to be sound.
