It also records the count of regions as a checksum. > While reading the list of recorded regions, if the checksum does not match the number of regions read at time {{t}}, then the plugin will move on to regions at time {{t - 1}}. However, the {{t-1}} computation in inefficient today, and leads to microsecond decrements. It can be improved to use the time at which the current set of regions were recorded. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
