Normalization
We sum all inputs in minutes, then normalize.
$$ \text{Total Min} = \sum (\pm \text{Row Minutes}) $$
$$ \text{Hours} = \lfloor \frac{\text{Total Min}}{60} \rfloor $$
$$ \text{Decimal} = \frac{\text{Total Min}}{60} $$
Example
2:30 + 45m = 150m + 45m = 195m
195m = 3 hours 15 minutes = 3.25 hours.
