Watering newly patched lawn with ocilating sprinkeler

Hi, ive just patched my lawn.  Dug the bits I wanted to do, put down grass seed, and put a thin layer of Irish Moss Peat on top.

I have an Ocilating Bar Sprinkley which covers the whole lawn.  I've been reading how often to water it and it seems 10 minutes 2/3 times a day.  The thing it is in the advice the picture they seem to show is a Fixed spray type and it seems to me the Oscillating sprinkler I have as it swings from one end of the garden to the other does not deliver as mutch water.  As its not massively hot at the moment I was going to go for 15 minutes morning and evening for the first couple of weeks and when I see a reasonable amount of sprouting go to 1/2c house every other day.  does this sound correct?

My lawn is a bit odd in terms of sunlight.  The sun hits one end around 1030 and takes until around midday to cover the lawn, so I went for shady lawn seed.
