@garritfra Today's (#4) was the first I didn't make a meal of. For some reason my brain hasn't been in gear and I've been misinterpreting things and making daft mistakes. E.g. I got the wrong answer y'day because I couldn't add up a list of numbers. I checked the actual logic, couldn't find a mistake (because there wasn't one!), emitted the list and added them in excel. Then spotted the spectacularly stupid error.
