@childofgod49 I've had good results by having a daily rep target for an exercise and completing it in whatever number of sets is necessary.
In your case, you might aim for 21 pull ups per day, and achieve that in sets of 6,6,6,3. You can then progress by doing 7,6,6,2 and so on, until you can achieve in 3x7, and then increase the daily rep target.
It means that you can keep steady progress by adding volume and not just by increasing the amount of work you can do in a static number of sets.
This was also a tip from kboges, though I think he reccomends a weekly rep target.
