Even very high waitlist have high chances of confirmation as there is only single quota is allotted no station other than Channai Central has charting rights.
So even if u r getting GNWL 100 from UJN to JP, it will confirm for sure!
Reason:
Suppose all berths are filled up including RAC and current status is GNWL 1/1.
Here...
more... it goes due to single station charting system:
2 pax from MAS to BZA will get GNWL 1/1 and GNWL 2/2.
Now status is GNWL 3/3 from MAS. But even from UJN also, it will show GNWL 3/3.
2 more pax: BZA to NGP gets GNWL 3/3, GNWL 4/4,
2 more pax: NGP to BPL gets GNWL 5/5, GNWL 6/6,
2 more pax: BPL to KOTA gets GNWL 7/7, GNWL 8/8,
2 more pax: KOTA to BKN gets GNWL 9/9, 10/10.
Therefore only 2 berths are needed but it is showing till GNWL 10...
