Different services publish each value in point-estimate or range-estimate

KMA issues forecasts precipitation in levels such as 30mm-50mm/50mm+(range-estimate) rather than the Xmm (point-estimate)
OpenWeatherMap issues point-estimate precipitation

Possible solutions

use raw value if it exists
the medium of the range as forecast value
extreme value of the range as forecast value(to penalize ranges too wide)
random value of the range as forecast value(to penalize ranges too wide, subject to inconsistency)
treat wide range value as NULL and do not compute metrics
