Not sure why the writers looked at Data to determine how Spock should act. But they did. They introduce spock as he uses the word "query." And Data on the bridge of the pilot of TNG using "inquiry" about the word "snoop." And then they have Spock giving a computer-like countdown of the years, days, hours, and minutes that Data did routinely to the annoyance of others.
In the pilot episode, some of the speech was fast, too. Perhaps trying to fit in everything in the script without making more cuts and edits. Such as when Spock was briefing the captain after he beamed to the ship.
