A great reference! ^
I've lost count of the number of times people come to this forum and say...'...but Seatguru says'.
I emailed seatguru about 3 times over 18 months to let them know that their then config for the 777-300 (recliners, rows in the 20s in J) was incorrect and hadn't existed since 2009. Finally they updated it 2 years after the fact.
There should me an immediate ban for anyone that reads this thread then says..."but Seatguru says..."!
