The report is definitely worth reading although I don't think the data is strong enough to draw significant conclusions from. I personally think that this should be studied more in depth over a longer time period since the current study had a 50 hour threshold (not exactly but close enough). One thing which is mentioned in the research paper[1] is:

> However, we see positive speedup for the one developer who has more than 50 hours of Cursor experience, so it’s plausible that there is a high skill ceiling for using Cursor, such that developers with significant experience see positive speedup.
