I am not very familiar with the pros and cons of submitting a conference paper in the first round vs second round. In particular I am referring to the dates given for FG 2021 here - http://iab-rubric.org/fg2021/important_dates.html.
I would prefer to submit in the second round as it gives me more time. However, is there a chance that there would be no second round if sufficient papers have been accepted in the first round? Could someone briefly explain to me the first round and second round process. Thank you!
