Maybe the experience of the first-time-showing-my-4Lz-and-landing-it at CoR made a good mental note for him... not like the 4S3T last season so.. he's confident
On the other hand with the Lz.. perhaps seeing a 12 year old kid landing it makes him feel the same when he saw Mao *a*female* landing 3A.. hence the hanyu brain works itself with its theories...
