This isn’t the exact same, but there’s a similarity in order-of-magnitude differences and flow rates: Most professional pilots work for the airlines. When you remove military, it’s a huge majority. Most pilot jobs flow into the airlines. It’s a pretty cohesive labor market.

So, whatever market forces are going on for pilot labor in your little niche job are completely dominated by the airlines. Like you’d think banner towing jobs would be mostly affected by advertising trends, but they’re not. Passenger travel trends are way more important. (This is for the job market, not the business market)

Similarly, the flow from a way bigger site can overwhelm whatever you have going on.
