My impression is that top players would necessarily have a different study/practice regime than lower rated players, so if you meant useful for emulation I think it's questionable.
As for the site's management, it would be more useful knowing what features their paying members utilize the most and what features draw in non-paying members to buy a membership. I don't see how it would be beneficial to the ownership to know which features the strongest players use. Especially considering the site's features are not targeting the strongest players and that the larger (and more profitable) demographic to target is beginners.
I think it would be informative to know which features are used most by players in the top 10% by rating, and how they spend their time online e.g. 40% playing, 20% Chess Mentor, 10% tactics, etc. I think this would benefit everyone, including the staff at chess.com.
