Elite athlete criticizing mapping gets easily seen as a bad loser and whiner. It is pretty brave to do it on public forum. And if the criticizing pin points my personal pet peeve, ambiguous multi level form line mapping and it being standard violation, even better.
In 70s when I as a kid learned reading and drawing contours, one of the practices was drawing line on map and then drawing cross-section profile of it, and making playdough hills and drawing contours out of it and taking a map and trying to make playdough model of part of the map. Back then my resolution was form lines of maps mapped with this ambiguous style were pretty much useless, and even full contours were suspicious on those parst of the maps. There just was no way to interpret those parts in unambiguous way. Even my dad could not explain what or why really. I guess Biggins came to same resolution, CF ignores form lines when ocad file gets imported for 3D terrain modelling. Anyway, back then as a kid I wondered why such mapping is sometimes used and why there is no that much complaints about it. So if now 40 years later one of the best does it. So of course he is hero to the kid in me ! :)
I have other heroes too. Olav of course, for pinpointing sprint mapping issues, remember how he DQs himself after running on microscopic olive green. And TGIF for pinpointing course design/mapping issues like the woc long second leg over impassable stream. Even if I don't agree with the idea of making such rivers symbols forbidden (that would not fix the issue, there is better alternatives like the example he linked), this pin pointing the problem is right thing to do and also brave thing to do for the risk of getting seen as a whiner. But these hasn't been my personal pet peeves since 70's.
