 It is difficult to know where to start with the I term. Usually it ends up being 1/3 to 1/2 of the P term once tuned (on my quads). Also I find it doesn't need to vary much when P and D are changing, it is almost an independent setting from P and D. Start as low as you are comfortable with. Before you fly a newly-built quad, it is almost impossible to know where to start, unless you have built a similar one before, or someone gives you some starting values. In the case where there is nothing to start with, you have to put some numbers in there and just see what happens. It is difficult to know where to start with the I term.

 +"I sometimes start at zero to see how balanced the quad is. Otherwise if I can't balance the quad or I just don't feel like havig drifts, I just put 1 in there, that stops the drifts.\\
 +However, low I seems good in gentle flights, but will be bad as soon as heavy maneuvering starts. Generally the quad tends to want to come back after a rate change with I too low."
  
 Also, you don't have to tune a quad and that's it (in one go). If you keep notes, you can keep tweaking it when you are in the mood to try some changes. Some quads I almost gave up on turned out to be great flyers in the end, given a bit of time and persistence, but not all at the same time, (or on the same day), sometimes it's weeks later until I get it flying right. Others quads, they are tolerant of many tuning values and fly well right from the start.\\ Also, you don't have to tune a quad and that's it (in one go).
