Here is a good that explains AM in pretty good laymens terms. The funny thing is, this what written by engineers and never once do they state anything above 100%. They even mention flat topping toward the bottom(and because fatty wont read the whole thing, Ill copy and paste.....

"I am sure many other hams were/are also unaware, and just assumed that if you hit 100% on negative peaks you automatically hit 100% on positive peaks as well, with voice modulation as well as a sine wave tone. So I could have been running my audio either way. I'm sure many cases of unexplained splatter result from the high positive peaks trying to drive a transmitter capable of modulating only 100% positive, resulting in flat-topping, which causes about as much splatter as negative over-modulation. So two hams could each have a KW transmitter modulated 100% as indicated by a negative peak flasher, and one transmitter be will within the limit, while the other kicked the peak meter off scale, and lacking knowledge of the asymmetry factor, be completely baffled to explain why."
