Years ago I wrote short stories. For many of these I now look back and cringe. For this question, I suspect I shall look back at it similarly. However I think it's important to record this otherwise I'll have nothing to look back on, which is worse.
As is often the case when I am in Germany, the topic of (painful) train travel came up, and in particular: is it quicker to go North↔South or East↔West? Me being me, I wondered if I could answer this with data.
