When I first started stat-tracking, I too kept track of double-teams. The problem is, they aren't very informative. Some players turn the ball over when doubled. Some shoot. Some make late passes. Some (the great creators) immediately find the weak spot in the defense with a pass -- that's what matters most. In this sense, double-teams by themselves are really a function of defensive strategy.
Most of the doubles were really a function of the scheme. Both Shaq and Hakeem were not penetrating the defense and creating shots for teammates. They got their doubles and passed it to the open teammate if the opponent committed too much to them in the post.
(IE Do you count it as a double when a defender needs help because his man dribble by him or because he was stuck on a screen? These are the actions that scramble defenses...)
I have 2 criteria for a double team:
1. Did the ballhandler see the double team coming?
2. Did the double have some kind of effect on the ballhandler
If it fit one of those, I counted it as a double. If they doubled but it came late and Shaq/Hakeem never saw it, I didn't count that as a double.
I kept track of 2 kinds of doubles. Ones that happen before any shot can be taken and doubles during the shot.
As far as the man dribbling by him and scoring, I do count it as a double team if both of them are close to the ballhandler. If he misses the shot, I give credit to the help defender. If Shaq/Hakeem had to play help defense on an opponent who drove to the basket, and they left their man open as a result, I labeled that as open shot and didn't ding them if they made a legitimate help play.
As far as screens, I don't recall a situation where that happened. Big men don't handle the ball in the PnR so they never got doubled coming off the PnR. However there were a few instances where Shaq doubled the ballhandler and one of Shaq's teammates had to rotate to guard Hakeem. If they established themselves, I counted the shot against them.
