And wow, answering all that was a crazy ride!

It took a total of 7 hours 43 minutes to think and write all the answers (including gathering the data and numbers to answer accurately).

Plus, gathering the screenshots led to finding out about a critical system failure on our app, which took me 94 minutes to fix, so that was a pretty full Sunday all-in-all :)
