A change of 4 or 5 percentage points will change the feel and elasticity properties of the dough quite a bit. If you are asking what the term "hydration percentage" means, it is the weight of water divided by the weight of all the flour. So 700 grams of water in 1000g of flour is a (baker's) percentage of 70%.
