-Why doesn't "costlimit" simply redefine the existing "sizelimit"?
+Why doesn't "weightlimit" simply redefine the existing "sizelimit"?
 * "sizelimit" is already enforced by clients by counting the sum of bytes in transactions' "data" keys.
-* Servers may wish to limit the overall size of a block, independently from the "cost" of the block.
+* Servers may wish to limit the overall size of a block, independently from the "weight" of the block.
 
-Why is "sigoplimit" redefined instead of a new "sigopcostlimit" being added?
-* The old limit was already arbitrarily defined, and could not be counted by clients on their own anyway. The concept of "sigop cost" is merely a change in the arbitrary formula used.

 Why is "sigoplimit" divided by 4?
 * To resemble the previous values. (FIXME: is this a good reason? maybe we shouldn't divide it?)
