Overall, it probably won't affect it much. The final VRF for combined runs will be greater than or equal to the sum of the VRFs for the individuals.

Hi,
We had a question about multiple runs and optseq. If we compute our sequence as one long 12 minute run, then we get a sequence with a VRF around 25. But of course, that's too long and we would want to split it into two. If we calculate a run half as long, then we get a VRF around 10.
If we split our long run into two, how would that affect our efficiency? If we calculate the sequence as two short runs, how does the power of the two add up when you analyze them together (after concatenating the two short sessions)?
