Pre-Match deadline - oceanwave

[ArchivalUser]

Is Jan 31st technically the deadline till when a program can offer a pre-match? Becoz they have to update their quota by then? or if I put it another way, can programs offer a pre-match anytime before the submission of the ROL, which is feb 25?
Anyone who has a better understanding of this, please explain..
Many thanks!

Seems like they have to do it before jan 31....it just makes the most sense.
