Strange trend in sales

So I hear there have been new licensing options available to pond5 clients. i havent really looked into it much, and i have noticed a few composers on here who are complaining of a lack of sales since these new options came into place. Oddly enough, my sales have skyrocketed over the last few months. i have around 300+ tracks in my library and I always got around 4-5 syncs/sales a month for over 2 years. But ever since late august of this year I have been getting 2 week spurts of daily sales with a few week long dead periods in between. As you can expect I have been pleasantly suprised with this trend, but noticing how many other people on here who are experiencing the complete opposite has me raising my eyebrows. Anyone care to share their experiences or their opinions on this?

I wouldn't put too much thought into these things.
