Hi!
MacDive shows the ascent rate in units per second (meters per second for metric, feet per second for imperial). However the ascent rate is typically talked about in units per minute, and the values shown by MacDive get rather small and rather imprecise. For example, an ascent rate of 5 m/min is shown as 0.08 m/s. It would be nice if these measurements used per-minute values instead, like the SAC/RMV etc.
I'm also wondering about the thresholds for ascent rate warnings in the graph. Here's an example of an orange-highlighted ascent:
I'm going from 10m to 5m in 1:20, so 3.75 m/min. That's far below the usually recommended 10 m/min -- why the highlight? (I can see there's a slight sawtoothiness to it, but even the individual segments are not close to warning rates, IMHO.)

I've noticed that ascent rate highlight a lot on my dives and double checking I was well within the allowed speed so same query from me.

Re: Improvements to ascent rate measurement / visualizations
Same observation and same question from me. I can turn off the warning on the graph but I'd like to know what triggers it in the first place.
