I would NOT conclude "flood gate opened" or "momentum her way". This WAS expected that some would send their acceptance at last minuit (acvounting for mail delivery time). So, I would think Wednesday WAS the peak people "sending" their letter and yesterday was the peak of them being received /added to register. IMO from here on is back to struggle for Gina to get from here to 50%.
And in case Gina didn't hear me before: I AM HOLDING.
