The FSW points system is the minimum criteria you have to meet and does not change.
The CRS points system ranks candidates in the pool to determine who is chosen for PR, and goes up and down depending on who is in the pool.
To meet the minimum requirements for Express Entry, you must have at least 67 points under the FSW points system. Your Express Entry score (CRS) then determines if you are selected out of the pool of candidates. Only those with the highest CRS scores are selected. Right now this means you need 460+ CRS points to be selected.
BTW: I'm not a "sir".
