Questions about offset and overreading

I've been using EAC to rip my CD collection and when I first configured AccurateRip it came up with an offset of +102, which I've been using for about 200 discs.  I was reading up about overreading the lead-in/lead-out and decided to test my drive, which apparently dose overread the lead-in, but with the 2 discs I tested I got one offset in the +2000s and one in the +3000s.  So, question 1, should I be worried that I've been ripping a bunch of CDs with the wrong offset?  And question 2, are there any situations where I'm losing audio data with the positive offset and the inability to overread the lead-out?

If read sample offset correction is positive and your drive cannot overread into Lead-Out then the 'Overread into Lead-In and Lead-Out' setting should be disabled.

Overread Lead-In and Lead-Out : Press the button that says "Detect read sample offset correction". Enable this setting if it says your drive can overread from both the Lead-In and Lead-Out or if it says Lead-Out and your offset correction is positive or if it says Lead-In and your offset correction is negative. Otherwise disable it.

1. Are you sure your tests (whatever they were) aren't showing alternate pressing offsets?

Fill up missing offset samples with silence : Checked
The last 102 samples of the last track will be replaced with silence when your drive cannot overread into Lead-Out. This tiny fraction of a second is likely inaudible or contains silence anyway.
