I would usually discard those levels that are only 2 levels long since they are a bit short, but the few other ones are really noteworthy.

Levels 76 ~ 79 is a mini cluster that is a bit hard, and a pretty long chain.

Levels 181~182 used to be part of an even longer chain called "Hell's cluster", between 180 and 184. Back then, 183 & 184 were a lot harder than they are now.
