Hi,
Very minor nitpick but probably very easy to fix: The dry/maillard/dev bars at the top of the graph don’t round properly.
EG, here’s an example of a roast that had 24.8% dev time, but shows in the phase bar as 24% (2:33/10:15 = 24.8%) It should probably be 25% if no decimals are shown-- that would be more intuitive for most users.
