You make the valid point that pros can and do hit the ball further than their average distance when they want/need to. Also that it's not the distance they hit their clubs that makes them a pro, but their ability to score.
On the flipside, people continue to pull arbitrary swing %s out of nowhere as a way to claim that guys not on tour could hit it as far as they claim to, because tour pros really hit it xx yards further than they actually do.
The reality is that pros do not hold back hitting 50 yards as far as they can the majority of the time they swing. It's simply not in their best interest to do so. They do not swing out of their shoes because their accuracy would suffer and so would their average distances.
So, while they could possibly hit the ball an average of 10 yards further with any given club xx times out of 10, they could also risk a mishit or an offline hit that goes 10 yards shorter xx times out of 10. Pros are human, they also hit bad shots. Assuming that they swing "110%" all of the time won't result in them hitting their 4i 30 yards further than their average every time. If it did, they would do it. That way they wouldn't have to hit their 3w or driver on that particular shot.
