so..... the data this is based on is from https://sci-hub.se/10.1109/vlhcc.2014.6883030 which is 21 students programming.

Seems a bit suspect the whole premise really. I don't really end up doing what this article outlines. I find a lot of programming studies are often done on what is immediately available... students, and I think this tends to not really be indicator of what experienced programmers do.
