Dear Piscess16,
the Miner will mine in the first 4 Minutes for our fee. Then it will mine for 200 Minutes on your pools and will continue from there.
This is equivalent of ~ 1.96 % of the Mining time. (4/204)
For the T9+, we haven't done testing on a T9+, the T9 is very efficient and might be comparable.
Thank you for your question,
Your
