The reports come from long-term owners in enthusiast communities and forums, the same reports behind our product verdicts. Each report is sorted by topic and counted once per topic, as a problem when it describes a failure or an annoyance. A share is the number of reports raising a problem divided by all reports in that category.
A category appears once it has at least 30 owner reports and two problems raised by several owners, and a model is compared once it has at least 10 reports. The counts refresh when the verdicts behind them are revised.
