I think the only explanation is someone "declined" a previous ITA which effectively put them back into the pool. There should be very little people left above 451 at this moment.
Scary thing is we are seeing record number of people joining...with CIC skipping draws it could be game over for some... I predicted beginning of the year that we
WONT go below
428 this year... but I really hope I'm wrong as I want everyone to stay hopeful!
Congrats to everyone receiving an ITA !
