Is “time until sold out” a good indicator of high ROI for new NFT projects? If so, how long is a desired one?

I'm wondering what signals indicates that a new NFT project has probably a high ROI.

One of that signals that I'm analysing is time untill sold out, do you think that how long it would be a desired sold out time to indicate that a new project is very profitable and with a high ROI?

I'm noticing that outstanding projects sould out between about 40 min and 2 hours, while projects that takes more than 18h to sold out it tends to remain in a low price floor, so would "time until sold out" be a good indicator of high ROI NFT projects? If so, how long do you guys think it would be a good indicator? 3h?
