Hey Craig, I am not an expert but I stick to 14 days.... however, it depends on individuals style of trading... Bad example but i wud like to give one example... 5 people making tea with the same amount of ingredients but still taste differs... so the same way, I may be performing good with 14 days and others may not and vice versa...
Good Luck,
Apurv
