Oh boy, this sent me down a memory lane. I remember arguing long and hard with my math teacher in elementary school that "two times as massive" and "two times more massive than" are not the same thing, but she did not agree. That's the point where I learned that the grownup world is weird and sometimes it's easier to just smile and nod.

would you say the same for "33 times longer"? that ut means "34 times the length"?

for me "more X" and "Xer" are the same thing, so I don't get your system
