If I've missed something obvious, then by all means help me to understand your meaning. However, if you are unable to defend what you have written without becoming defensive when questioned on it, then simply do not write it.
I was truly surprised by your ignorance on this topic, Rob. And, just to be clear, I never feel compelled to defend any position I may have on a
discussion forum as this is a discussion forum, not a court of law. While that could be translated as "I can say whatever the h*** I want", it's not the tact I choose to take. Reasoned thought, I find, is most productive here. Boring for some who like to unnecessarily stir the pot, but helpful to the vast majority here who come to learn and not be pounced upon as it seems I did, quite unintentionally, to you. So, to answer your query....
It may sound pedantic, but what sometimes happens with photographers using zoom lenses is they choose specific focal lengths that match their vision of the scene, often based on focal lengths they may be familiar with through prior experience; e.g. 35mm or 50mm on a 24-85mm zoom. This would show up as a predominance of photos taken at specific focal lengths.
In the OP's case, he is using the zoom primarily at extremes. This, too, is not unusual and accounts for the dearth of photos at in-between focal lengths. The use of extremes may also indicate a user who would benefit from wider or longer focal lengths than the lens allows.
SZRitter points out a different use of zooms which results in a different profile of focal lengths. Someone who stands in one place and zooms to crop will have, perhaps, more photos between the two extremes and at more random focal lengths.
Of course, one can use a zoom in any number of different ways and completely ignore this over-analysis. Being completely free of the constraints of focal length is one of the advantages of zooms, but as I quoted in my original post from Orson Welles, "The enemy of art is the absence of limitations."
