For the Powerbook Unusual Lines 2022, 649,000 games from the engine room were used, plus 51,000 games from the Mega Database 2022 and the Correspondence Database 2022, together over 700,000 game starts. To ensure a high reliability of the statistics, the recording threshold for the games was set at 2350. The ECO codes A00-A09 include the respectable moves 1.Sf3 and 1.b3 as well as the harmless game beginnings 1.g3, 1.f4, 1.b4, 1.a3 and 1.e3. But one can also study such dubious moves as 1.g4, 1.Sa3 etc. in large numbers.
