But does moving the sliding bar change whether you are leaving under PVR terms or not?
If you set your leaving age at 60 and then slide the bar back, I assume it doesn't take into account the reduction in pension caused by leaving early. That could give someone a nasty shock if it doesn't.
Not being able to set a future PAS date means that the tool is effectively useless for pension forecast planning for those due to change over in the next few years.
