It will become more and more obvious with every subsequent post, but I feel I should at least loosely define the scale I'm using.
A ranking of 100 means that it is a feat where someone or something of around 100 to 200 pounds is being hefted.
A ranking of 200 means something from 200 to 400 pounds.
A ranking of 300, however, covers an event that requires 800 lbs or more of force all the way to the greatest feats that normal people can achieve.
The 400 ranking is the high end of what Spider-man could do back in the day.
500 requires the force of some heavy object like a car plus acceleration, or some huge object of tank mass or better.
600 Steel of great thickness, gargantuan objects.
650 Orbital launching of level 400 objects
700 Hefting or catching of immense building-sized objects
800, 800+ = ???
(Stay tuned...)
