ACK, this is not only "supposed" to be, but already per definitionem.
link quality == good packets / ( good packets + lost packets )

in the anglo-american language domain this concept is known as "bernoulli

in the german lang. domain the word "quality" in this context is rather "güte"
(in the technical sense of the word) than "qualität". and the concept is quite 
commonly known as:

"anzahl der günstigen fälle dividiert durch die anzahl aller möglichen fälle"

as stated a while ago, the current olsrd linkquality concept is
voodoo magic, but not sound theory ;)
