And pro fitter Steve Hogg explains why and it's because the riders are subconsciously dropping their heels in difficult climbs. He even goes to recommend to adjust the saddle height based on the amount you're dropping your heel on a hard climb and if he's accurate about that statement, that means the majority of recreational riders have set their saddles too high - that might explain why many recreational riders develop knee issues after many years of riding.

To avoid reading the entire page, the topic is found in the middle paragraphs under the title heading "How to set seat height accurately if you are a bike fitter"
.
This renowned London based bike fitter agrees that most recreational riders have their saddle set too high. He reckons about 90% of the "men" that come to him for a pro bike fit have their saddle way too high. He goes on to say that he typically lowers their saddles by on average 20 mm, so there is obviously quite a culture (at least in London!) of riding with a high saddle. I strongly suspect it's a macho "pro look" thing, as with slammed stems.
