Ganito kasi yun, yung base ng analysis nila ay as of Aug. 5, 2017. So if you are on queue for 6 months as of August 5, 2017, probably 5 months from August 5, you will receive an ITA.
Ang sakin ay let's say 9 months on queue, so I'll be expecting less than 5 months to receive an ITA.
More or less than 1 month (+- 1 month) accuracy for me is quite good as a forecast.
