I've got HomePlug AV a TP-Link 210 kit, I get about 45Mbit between PCs on the network. That's with the HomePlug connecting at (allegedly) 170Mbit.
You have to remember that 200Mbit is the max speed, and it's the MAC speed, so the symbol rate, you'd get about half the speed your plugs connect at. AV2 is faster, so if you got 34Mbit you will possibly get up to about 68Mbit on AV2.
