Measurement logic behind getPageLoadTime plugin

[AdamRobC]

Hi, we recently implemented page load speed tracking using the getPageLoadTime plugin:

Does anyone know what the measurement logic is behind this? Is it total page load? DOM Ready etc.

Taking a quick look at the plugin it seems like it is getting the delta between window.performance.timing.navigationStart and window.performance.timing.loadEventEnd.

(when the load event completed on current page) - (right after the unload completed on the previous page)
