Differences between the ease with which a less practiced person may accomplish various feats are not unrelated to differences between the ease with which a more practiced person may accomplish various feats.
To illustrate meaning: suppose you have a one yard, three yard, and five yard pit to jump, and you tell a bunch unathletic people to go across; most people will probably pick the one yard pit, because it's easier. A champion long jumper could certainly jump a lot further than any of those people; he might well be able to clear the five yard pit even; but taking the one yard pit would still be easier for him all the same, just like it is for the rest of the group too.
