I want to set up a goal that has to do with intermittent fasting.
I want to fast 16 hours a day, i.e. only eat within 8 hours a day.
For that, I need to subtract the first datapoint from the last. Or (same thing for me) subtract smallest from largest.
Clocky comes close, but isn’t perfect, because with clocky, I’ll have to go back and edit my datapoints in case I had a late night snack.
(For those curious, there is now pretty solid science behind intermittent fasting, and I want to build up to 20 hours of fasting a day and more. Ask and I’ll post references).
