Phase 1 has released the dataset , and how to appy a cut-off to limit Phase 2?

Hi organizers,

It is apparently there are two teams in Track 1 now (April 30th), use the public testset [1] to obtain nearly full score (~0.98). I am wondering in this senario, how to apply a cut-off in Phase 2? Every participant just need to upload public testset and obtain the similar full score. Is there still potential cut-off?
