I have to disagree with you on that. According to my stats the highest i ever reached after almost 4 years is 1.13 average. I've had an average of more than 1 only twice in this period. This month is already down to 0,83 average, due to too much sub sales and level one images on lowest resolution. I noticed that once an image reaches a higher level per picture sales become rare and those are downloaded most under subscription.
No, I'd agree with Dan __ my average sale price is continuing to rise as more images reach the higher levels. Here's the last year;
