can we simply ignore daily pivot low cracks if the Weekly pivot low is still intact
Nope, can't do that. With this method you will never be able to decide on your position sizing! Plus you will be in a really bad shape if the market majorly crashes while you wait for your weekly confirmation.
You said : "My query is that to recognize a pivot can we keep a certain percentage say 10% ...."
Saint has defined his stop as the pivot low. It works for him. I believe, there is no one method. You are free to apply any other sound logic for your stops. But whatever you do... follow ur STOPS strictly. (And yes, kindly share your logic for arriving at this figure of 10%)
