Eh so you need to be killing the game just to win back what you lose on the rakes? -Or if say 5BB/100 is killing the game.. then what is 7.5BB/100? (which is already 50% better) Absolutely butchering it beyond recognition? And 10BB/100? No words to describe it anymore?..

While I totally agree that -10 til 0 BB/100 is average (due to rakes, more people have to lose than win), I think certain terms here might be a bit misleading..
