Time zones are expressed in hours ahead of UTC (see timeanddate.com). The “evaluation” column is an educated guess based on the number of potential participants living near the smallest hub or the likelihood of participants traveling to the smallest hub without flying. The table is different in summer and winter and may change from month to month due to variations in DST.
