Is there something screwy with lurve ratings?

Over night, I got lurve from 5 different GAs and one question that I asked. Yet, my lurve score only went up 10 points. This isn’t the first time it’s happened either. Before, I thought it was just accidental duplicate lurve because it was from the same answer given, but this time it’s all different answers. I’ve been keeping an eye on it. I usually let it slide, but that’s, as Led Zepplin once said “A Whole Lotta Lurve.” What’sa matta wichu, Fluther? Does this happen to everyone?
