@loweel @fribbledom Right, so to answer @TauPan specifically ( mastodon.technology/@TauPan/10… ) it doesn't really stop working "at some point", and not at 100 km or miles, it's at its worst just before and after 8/5 and then from 34/21 onward it goes from about 0.6% wrong to about 0.5% wrong for the rest of the series.
