Gemini doesn't charge a fee, but to do a test, I withdrew USD $100

My Bank received only USD 93, and after receiving the amount it charged me a additional USD 7 as incoming wire fees.
So net I received only USD 84 on a USD 100 withdrawal.

So there were two fees
1. By Gemini's intermediary bank or the bank used to wire the money over via SWIFT  (Question: Does anyone know what's slabs for bank used by Gemini for intl wire)
2. By my Bank which is $7 fixed fee for any amount
 
Does anyone know what are the wire charges slabs, is it fixed fee or depends on the amount. The fee's of USD 7 charged by the Gemini bank's intermediary, is that going to be the same say If i want to transfer 5000 or higher amount etc.  

Has anyone tried to withdraw over ten thousand to a USD bank account outside of the United states ?
