Sorry for the late reply, Allin. Yes that looks good to me.
But would "permanent sub-sampling" mean that this only applies when executing
the smpl command with the --permanent flag? Or would it also apply when
storing a sub-sampled data set?
I favour doing this only when the --permanent option is given. It's
an information-destroying move, and I can imagine cases where one
wants to save a sub-sample and yet not lose the information in
question. But if you _want_ to lose it, without using --permanent,
then just store in a format other than gdt or gdtb.
