Gain = 0.16 meaning 1 electron results in 1/0.16 = 6.25 ADU
Read noise = 4e thus 4 x 6.25 = 25 ADU equalling about 5 bits (2^5) taken by read noise leaving me with 11 bits per sub for data?

that's the way I would do it Suavi. gosh that read noise is low
.
I think that the dynamic range data on the 1600 can be read off from the graphs on the ZWO website
