If you found/fixed a leak, clear codes and try to duplicate the problem. If you had a vac leak/MAF/fuel pressure problem your fuel trims would be off, which they are not. Either the problem is fixed or your Bank2 O2 is intermittently dropping out.
Instantaneous readings of O2 sensors are next to useless as a working O2 voltage jumps around considerably. Don't worry about the CSV file, your equal trims on both banks answer the questions.
It is hard to catch a bad O2 sometimes as the "dropout" can happen for 5-10 seconds at a time, sometimes more than a few minutes apart. I have had cars I had to drive 20-30 minutes to catch a bad O2.
