Function range_not_sampled_message 

pub fn range_not_sampled_message(
    requested_display: f64,
    reach_display: f64,
    unit: &str,
) -> String

The one wording every card surface uses when its solved flight supplies NONE of the rows asked for (MBA-1476) — stated in the caller’s display unit, because that is the unit the request named the range in.

A flight that supplies some but not all of them is not an error: the card prints the rows it has and says what it left out, via CardTruncation.
