Only one developer in this study had more than 50h of Cursor experience, including time spent using Cursor during the study. That one developer saw a 25% speed improvement.
Everyone else was an absolute Cursor beginner with barely any Cursor experience. I don't find it surprising that using tools they're unfamiliar with slows software engineers down.
I don't think this study can be used to reach any sort of conclusion on use of AI and development speed.
