We need to make a distinction between spillover from FB-> EB, and horizontal and vertial spillover within EB.
FB->EB is applied immediately at the start of the year. This spillover is spread to all countries, so the impact on any individual country is not much. However, they have been cautious applying horizontal and vertical spillover within EB, and have applied the horizontal spillover only towarads the end of the year. Although we know based on history this spillover is likely to be big, they have been extremely cautious just in case there is an unexpected surge in applications from ROW. So the cautious approach has its valid reasons and is in keeping with how its been done before, and the spirit of the law which allows horizontal spillover only after its certain it will not be used by ROW.
The good thing is if the applications have been adjudicated, the approval process is actually very quick once the dates are current. So the biggest factor now is just how quickly the cases are pre-adjudicated. If its like previous years, there should be an increase in pace of movement in the later half or last quarter.
