Yes, but what if the format turns out to not be exactly the same as shown? It's safer to record every raw capacity in turn, then if you run across Unassigned, add the raw capacity to the total: 
use strict;
use warnings;

my ($raw, $capacity, $unassigned);
while (<DATA>) {
    $raw = $1 if m/Raw capacity: (\d+\.\d+) GB/;
    if (m/Mode: Unassigned/) {
        $capacity += $raw;
        $unassigned++;
    }
}

print int ($capacity / $unassigned * 1000 + .5) / 1000;
