When I was setting out to the solve, I kept thinking I'd need to cold-solve everything before even starting to to the encoding, so if everybody had a similar mindset then you can see why they'd get up to 20+ clues cold-solved before anything else. But once I'd started, and perhaps once I'd also figured out *how* to apply the logic, it seemed to be steady progress from then on.
I mean, sure, it took me a while, and I was working on it until quite late. But that's because there was always just enough progress to tempt me into pressing on.
It's one of those puzzles where I can see how automation would be helpful, but it isn't necessary imo.
