A large saddle to bar drop might cause too much pressure on the hands, but so will inadequate midsection strength and other fitting mistakes, like placing the saddle too far forward. The most common fix for that mistake is to raise the bars with a larger frame, a taller head tube or a steep stem angle. You end up with two mistakes to produce a tolerable position.
I've been riding for over 25 years and used a saddle to bar drop of 9cm for a long time, but actually increased it to 11cm a few years ago, when I was 55.
The bottom line is that you can't predict the best frame size or bike setup by measuring a person.
