Doug KR2Q created the following data from the 2015 CQ WW CW Logs for top Multi-Single stations. The table shows how many QSOs were made by the multiplier station during each hour of the contest. In the CQ WW Multi-Single category, the multiplier station is only permitted to work new multipliers.  It is quite busy in the first day, but becomes much more difficult on the second day.
