I'd add a caveat to the distinction between those numbers for hoods and drops. You can typically be just as low on the hoods as on the drops of you bend your elbows and have your forearms parallel to the ground. Your body winds up just as aero and your arms more so.
If you watch pro racing you will see most riders doing that these days. When they do use the drops it is more likely to be for comfort or biomechanical reasons.
