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

Considering fractions might help you understand where he's coming from. If you say something is "0.5 times as long as a one meter thing" you would expect it to be 0.5 meters, but if it's "0.5 times longer than a one meter thing", you would expect it to be 1.5 meters. The same logic applies when you ditch fractions and use integers.

0.5 times longer is nonsense

0.5 times shorter makes sense
