I found this table to set x11 difficulty, but is that regular mh/s or x11 mh/s?

Miner Speed    Scrypt Password    Scrypt-N Password    X11 Password
0MHs - 1MHs    d=256    d=128    d=0.01
1MHs - 2MHs    d=512    d=256    d=0.02
2MHs - 4MHs    d=1024    d=512    d=0.04
4MHs - 8MHs    d=2048    d=1024    d=0.08
8MHs - 16MHs    d=4096    d=2048    d=0.16
16MHs - 32MHs    d=8192    d=4096    d=0.32
32MHs - 64MHs    d=16384    d=8192    d=0.64
64MHs - 128MHs    d=32768    d=16384    d=1.28


So my rig runs like 3.6mh/s on scrypt and 16mh/s on x11.

Should I set diff on 0.04 or 0.16?

Thanks
