I am still happily chugging through this one, so no idea as yet about possible controversy. And I have no idea whether my scrawled "e"s were suitable. But I can say that my whole year's endeavours have been blighted by what to me was the unfairly biased klein bottle farrago from last year. Perhaps I should lighten up, but the amount of effort I put in to getting to the impenetrable solution only to come across something that was only knowable if you knew it (my reaction!) made me heartily sick of the whole Listener thing, and unable some weeks to summon up the energy to bother with the minutiae of the endgame. I went from an aspiring all correct to an occasional submitter, lots of meh, and I am only just feeling my way back. The subject matter of 4198 was so partisan and trivial that the meh factor seemed to affect so many people here. To then turn round and say "Yah! You're all wrong because you fail to meet our standards of calligraphy" is childish, and likely to put more people off than encourage them.
