After float 1 u walk and do 2 leap its more plus than reg float1 so much harder to escape overall also better position due to 2 hitstun animation allow for true mixup off close leap:
1) close leap 1+3 can be backdashed
2) close leap 2 - crossup, can be fwd dashed
3) close leap 3 - not crossup. Unescapable. If opponent backdashes it can be punushed via d1-mc or d2. Cheetah is the only char that avoids this somehow.
Chances to guess right for opp are really low here as every option require different answer, probably 33%. The only thing you need to feel is range of 2-leap as d1 os is only possible at certain range and a lot of trait conversions tend to leave you at different distance. My tip is to look for range where grodd cleap 1+3 will land almost behind opponent but still grab him, also smth that s2 hitstun makes possible.
