That was my share, the total was $2750. Also, I didn't mention, but I paid $2k for my own one-bedroom for half that time. That same one-bedroom would be $3k today.
Salaries at Google have scaled with cost of living, so it seems relevant to me.
Saving that much money (even adjusted) in 4 years is totally realistic though, so I'd say it passes as anecdote.
