From memory, with the wholemeal one, you started it on day 1, and then fed it day 3, 4, 5 and on day 6 you had enough to make a loaf. One of the bakers at the Village Bakery in Melmerby also did the same thing starting with 1 little ball of dried yeast.
It seemed to be fairly sloppy
day 1 40g flour + 40g water
day 2 as day 1
day 3 40g flour and 20g water
day 4 120g white flour + 100g water
It can die if it becomes too acid. He suggests taking 130g of the old started and adding
60g w/meal flour
120g white flour
130g water
The production leaven is then
160g starter
50g wholemeal flour
150g white flour
120g water
He leaves this for 4 hours and then makes a loaf with
300g production leaven
100g wholemeal flour
7g salt
300g water
300g white flour
In making the final dough, he makes a dough with the other ingredients and, after kneading it, he then adds the production leaven.
Andrew Whitley, isn't in Melmerby any more, he has gone to Scotland, where he is still running his bread-making courses. He used to have a forum. He's really approachable, and I'm sure wouldn't mind you emailing him and asking him for advice. bread matters
I've been on 2 of his courses - the basic one and the sourdough one, although I haven't made any bread for ages. 
Good luck
