How do you read that quote as a positive thing? The first half merely says it was successful in collecting data and the second half uses weasel words "could improve".
I've worked on projects in the past where we collected a ton of data like this, gave it to some poor graduate student or post-doc to do a bunch of data wanking with it, only to produce throw-away papers in bad journals because even. Though it was a huge amount of data it wasn't good data.
