Since you don't want people answering your q except Glitchless, I'll give you an easy way to test it. Equip a chippie(35 delay) and place a sylvain(delay 5 sec) healing gem in play, and watch for a few minutes. See if one ever catches the other(aka, the heals get closer and closer together and then further apart). If they don't, 7 delay = 1 second

However, if they do, then the noobs who think it's 10 delay must be right!
