Tor over VPN help

[Alter94 0]

I'm just wondering if I did something wrong. In Eddie I went under preferences, proxy/tor, and changed the type to Tor. After launching the Tor browser I hit the test button and it was successful. I was even able to connect to a server afterwards and use Tor. However I still believe it's not working correctly because I was still able to access .onion sites and my Tor circuit kept changing, apparently. Every time I did a IP trace my exit IP was always a Tor exit node too. Also I keep hearing people talk about how slow Tor becomes when using this method, but my speeds were relatively normal. Also in theory, suppose I had another VPN and wanted to create a connection not only after the exit node but before the entry node too. Could I use one VPN to block the ISP and the other VPN to encrypt exit node traffic? Currently. Need some input, thanks.
