What is an adjustable heat anticipator set at?

Above: the heat anticipator pointer is set to about 0.45 Amps. Longest Heat-on Cycle. For the heat anticipator above, when we move the arm and contact fully to the left to the 1.2A (longest-on position) we will see the least current flow, least in-thermostat-heating, so we turn the actual heating system off later.
