Each host city gets six pillar scores from 0 to 100, compared across all host cities in the data. The location score is their weighted average; the weight presets are in the toolbar. The grade is relative: S = top 10% of host cities, A = next 20%, B = next 30%, C = next 25%, D = bottom 15%. Venues are matched to the municipality ccfddl names, so Long Beach is not Los Angeles.

Updates
The list is rebuilt every day from ccfddl, so new editions appear on their own. A host city seen for the first time is looked up automatically in the same source tables. Deadlines are shown in your local time; always confirm on the conference website.
