I have just done a good recourse page at Amckern.actionrealm.com for all those of you that are mappers in HL, and have ever want to find out what each RAD flag did to your RAD.
The site has 3 shots of each flag in action, with the number flags having a half - normal - and dubble RAD such as bounces being made 3 times, instead of the once.
The site also has a download of each compiled RAD flag in a small map (in fact the map that the screen shot was taken from) so enjoy
