If by this afternoon she can see 55-60% in her bag, then course of action depends on the game strategy she favors. Extend and put pressure on instos and some recalcitrants, or let the offer terminate and play the game differently.
If she gets close to 50%, my tip is, offer will be extended but not upped yet.
This is all speculation of course, and DYOR and all the other bla, bla...
ps not much time for research now, gut feeling may be of help.
