Emergency lists move 10 points of the CR Score from reputation to availability: 15% and 15%. Availability credits 24/7 hours, same-day service, weekend hours and weekly open hours. 24/7 electricians are listed first, then same-day, then the rest; ranks follow that order. Paid placement never changes a rank.
