The second review of PR #12 (after the suspect-run fix) found that the two BAR charts were still plotting runs they should not have been, while the curve chart and the tiles had been corrected. The page was contradicting itself. The ABV chart plotted the suspect run -------------------------------------- Run 12's impossible reading gives it an ABV of 18.64%. The chart's y axis went to 18.64, so the fifteen real bars were squashed into the bottom ~45% of the plot - while the "Strongest 8.53%" tile on the same page showed the correct figure. The chart now leaves the suspect runs out. The attenuation chart plotted the active runs ---------------------------------------------- An active run's attenuation is measured against its CURRENT gravity, so a brew that has just started shows a 0% bar. That is the absence of a result, not a result, and it sat directly above the table of finished brews. The chart now leaves the active runs out. Verified against the live data: ABV chart bars: bars=15 max=8.53 (was 16 bars, max 18.64) attenuation chart bars: bars=15 min=76.2 (was 17 bars, min 0) A suspect active run no longer vanishes --------------------------------------- The API flags suspect runs over EVERY run, so the charts leave them out. But the analysis page only looked at the finished ones, so an active run with a bad reading would be dropped from the charts and never listed in "Readings that need a second look" - it would disappear with no explanation anywhere. The analysis page now lists suspect active runs too. The figures say what they are based on -------------------------------------- - The analysis prose counted the non-suspect runs, not the ones that actually contributed a figure to the mean. It now counts the latter. - The history page's "Average ABV — across finished brews" was averaging 15 of 16 without saying so, while the analysis page said "16 brews (15 counted)". It now says "across 15 of 16 finished brews". - `/api/runs/<run_id>` carries the `suspect` and `active` flags that `/api/runs` does. 148 tests (up from 142).
