No worries!
It's the second time I've run this kind of study. It took a day or two the first time, but then I wanted to learn how to SQL so it was all part of that learning process.
This second run was supposed to be easier but ended up taking half a day, partly because it got interesting at the end and I had to do some manual work to produce that last chart. There's always something that pops up to investigate - the blockchain is a fascinating study into behaviour!
Wow-wa-weee-wa! Thanks for spreading your information. 👍
