I have observed one pattern for PPRs / MRs from NDVO.
On the first day (till second day, sometimes) of the week, NDVO showers few drops of PPRs (say, 3-4 on avg.) and then stops.
On the last day (second last day sometime) of the week, NDVO showers heavy rain of MR / RPRF and it continues for whole week at fluctuating but at constant intervals.
If this (personal) observation is true then still, May-June applicants (waiting for PPR) have long way to go but yah, they may expect good news on first two days of each week.!!
