All Nippon Airways Mileage Club - NRT-SIN in Y Class 30 Nov - Will Waitlist clear?

I have booked a pair of cheap tickets and returning to SIN from NRT on 30 Nov on NH901. I am currently waitlisted on "L" booking class. Ticketing dateline is 7 days from date of booking. When is the chance of my ticket cleared by the dateline? It has been 5 days since I was placed on waitlist.

I have checked seatcounter and noticed that only "G" and "L" class are sold out. Just checking if there is a chance of waitlist clearing? Thanks.
