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.
