Venstar Thermostat History Data

Pulling up the history on my T7900 Venstar thermostat and it seems odd that sometimes the cooling runtime totalizer increments even when a cooling cycle does not appear on the trend.
Has anyone else noticed this?
Is there a minimum time that the compressor has to run to be registered as a cooling cycle? I ask this because at times I’m seeing cooling cycles of just barely over a minute.
Also wanted to ask how “Thermostat Thermostat Temperature” is different than “Thermostat Current Temperature”.
