I've been at this for a week and my DR has improved to 2-4 dreams a night (from my original 1). My question is, when I get to the stage when I remember enough dreams a night, how long should I stay there until I start trying to LD?

In case you'd like to know (if you think it has relevance) this has been my dream count.
Day 1-1
Day 2-1
Day 3-1
Day 4-1
Day 5-3
Day 6-4
Day 7-2

Thanks
