The numbers are rounded to reduce precision.

"bridge-ips" CC=NUM,CC=NUM,... NL [At most once.]List of mappings from two-letter country codes to the number of unique IP addresses that have connected from that country to the bridge and which are no known relays, rounded up to the nearest multiple of 8.

From each number of unique IP addresses, subtract 4 to undo the binning operation that has been applied by the bridge.
