Approval rate of unregistered domain name submissions

in my marketplace dashboard I see that the current site-wide approval rate is 10%.

Suppose I keep submitting unregistered domain names, I try to submit only quality brandable .com domains, and I always choose the option “I prefer to register the domain name myself”, then in the long run should I experience this same 10% approval rate?

Or the approval rate of unregistered domains are lower than the average?

Can you share your average approval rate when submitting unregistered domains?
