To be fair, models are more accurate than how they were earlier this year. In march I was still frustrated and was writing my own event loops because the model simply wasn't built for it. By January I was still hand checking statistical outputs to make sure it wasn't making any errors, and it was. After august it was pretty much over. There were no stats errors, code generated was shit but it could do what is asked. Instruction following is still a problem, and I sometimes catch silly things in the scrolling diffs, but it has been much easier since then.
