Copy this lines into your preload_alerts.txt and use both methods to see which one is more accurate (only one method works not both, so you need to comment the lines below and restart the hud for testing).
I think preload_alerts.txt is more accurate but dunno for sure, you must test and see, and i also think that is something wrong with the PreloadAlertPlugin code, but that needs a pro coder attention.
You can also try to fix the PreloadAlertPlugin code.
