I got 3.2. Spoilers below. Round 1 I just guessed in the middle of the 70s. Round 2 I was 5 years off, but I should have been able to get closer if I'd slowed down. Someone with a better knowledge of modern Middle Eastern uprisings or Arabic could have read the signs, but also the tech in everyone's hands was pretty closely dated. Round 3 was pretty clearly the London Blitz—the uniform was WW2 era and people were piled on top of each other in a London Tube station—which narrowed it down to basically a single year. Round 4 was another guess-the-decade shot, I was 6 years off (I guessed 1940). Had I thought about it harder it would have been unlikely to have been taken during WW2, which would have bumped my guess up a few years to be closer. Round 5 was a bunch of protesters who were pretty clearly in the mid-to-late 2000s (cell phone in the background), and the topic of their protest was gay marriage which had a single very important flashpoint in that decade with Prop 8 in 2008.
