This demo uses local storage to register prerenders, and then reports them (to the console, rather than via a beacon) from the calling page when you switch tabs or navigate away.
If you navigate to a same-origin page, the console will report the number of prerenders and activations for the referring page.
If you navigate to a cross-origin page, the totals will be logged in the console. You will need to click back to see them.
Note: this demo does not handle multiple tabs opening the same page.
