Indeed it does.
I've flow aircraft where the book says use an approach speed of 45-50knots depending on the likelihood of wind gradient. Instructors then tell students to approach at 55knots. Someone tells an early hours pilot that adding "5knots for the wife and kids" is a good idea and you end up with an approach flown at 60knots when it should have been 45knots! And they are surprised by how far it floats, or they get caught out by a big ballooned landing...
Stick and Rudder has a whole chapter about why it is important to fly at the right speed for the particular phase of flight and condition of the aircraft.
