you really can't as an Artist know or test prices in an Accurate or meaningful way, only the platform can know that for sure (CGT),
1000 model won't eve provide a good indicator, you need a wide range of 3d models with different qualities and prices and a big platform to analyse the market over a year or more.
i wish CGT would provide better analytics than they have now, it's really meaningless and doesn't help at all.
i use TS Analytics to somehow know the trends in the marketplace
