The difference in file size may depend on how many nodes are in the model. If the number of nodes increased by a factor of 1000 because the element size was reduced by a factor of 10 for example, you might find the result file size of the Transient becomes larger than the MSUP. I don't know for sure, but that would be an easy experiment for you to try.
