I liked how Gunnar wrote pretty much all of the code on the fly as we were going through, but that there was plenty of pre-prepared material on the google drive that I can refer to after the training. The code Gunnar wrote based on the sample data I provided beforehand was also extremely useful and also made the training relevant to our own datasets.

The trainer's subject knowledge was excellent, and the way the sessions were set out so that the audience could follow along with the demonstrations really helped to cement that knowledge, compared to just sitting and listening.
