Converts hop count to %. 1 hop is around 2%, 30 or more is 75%.
traceroute default max hop count is 30; left unchanged here as tracing over 30 is sloooow, but 30 hops will be converted to 75% only - sites in far east etc often have over 50 hops from Europe!
- Question - is there a way of getting a more accurate hopcount for sites with 30 or more hops, without having to go thru very slow traceroute count?
