Based on your analogue they drive the car for 7.5 inches (614.4 Kb by 63360 inches by 20 divided by 103179878.4 Kb) and promise based on that that car travels 20mph which might be true, yes, but the scale disproportion is too considerable to not require tests. This is not maths, this is a real physical device - how would it would behave on larger real data remains to be seen.

106 Gbps

They get to this result on 0.6 MB of data (paper, page 5)

They even say:

Moreover, there is no need to evaluate our design with datasets larger than the ones we have used; we achieve steady state performance with our datasets

This requires an explanation. I do see the need - if you promise 100Gbps you need to process at least a few Tbs.
