A little OT but I'd like to know what part about getting map info is too difficult to automate. Are they lacking the recordings or what? I'd love to see the maps included in the dataset.
Yes, most matches aren't recorded (at Genesis 5, a recent tournament, there were ~1400 Melee singles entries, for ~2800 matches. Of those, maybe 10% were recorded, most of those among the top 128 players attending.)
