When it came to Heavensward... and ARR for that matter...

I was usually at least a good 2-3 levels ahead of the levels for the Main Story Quest. But then again... I did do Dungeon Roulettes and did pretty much every Fate I ran into... which was a surprising amount as they were always in my way.

By the time I started Heavensward... after the full ARR and its extended stories after the Main Quest culminates in the defeat of the Garleans... I was level 54 and the quests were at level 50... when I made it finally to the Heavensward after the Betrayal which ends the ARR campaign.
