Timing violations - TimeQuest vs. Compile results ?????

I am pretty new to working with TimeQuest and working out timing violation in a design. In our current design we seem to be having some timing issues so I started looking at the TimeQuest analyser. ...

Sorry I was not clear.

When I added a multicycle constraint and the latch edge is shifted to the right relative to the launch edge I then tried to check within the design that the desired result will not be impacted.

However I don't understand that when I run the constraints in TimeQuest and shows me that the setup violations are reduced, then when I do a compile with the same restraints the FMAX gets worse and doesn't improve and also there doesn't seem to be an improvement in the setup violations in the same magnitude as which I received in the TimeQuest ?
