Dear Steve et al.

Yes, it is a choice about complexity vs efficiency of space. Using an
indirection to point to t means that you don't have to make the trajectories
all exist at all times. It takes very little more space: instead of the t(o)
in the usual trajectory feature, you have tindex(o), and this can then be
packed either in the start:stop contiguous representation or the indexed
representation. Extra space is needed only because there is a t variable as
well. But it is certainly more complex having this indirection. Does the
saving of space through not padding the trajectories justify the complexity?
I don't know.

Cheers

Jonathan
