These sentences read a little odd to me. The meaning is clear, but can "to" commonly stand in for "compared to"? If this indeed is a common usage, some other example sentences would be helpful. Or are these sentences uncommon instances of ellipsis? Also, what is the function of the boldfaced parts? Adverbial complement?
