Good day at work where I actually got my head around a couple of unfamiliar things and ran a few systems which provided slightly different results but landed on the correct one when reverse engineering previous results.

Well, it made me happy. Mrs C spent her day on Teams so I was marginally restricted in what I could do so left it until late on, whereupon I crashed out shortly after I finished. I did have a huge piece of a phenomenal fish pie, mind, so that's going to be a factor......
