So you have nearly 3,000 cards that would all grade exactly the same? If not, you might be doing what people are complaining about and misrepresenting your collection for the sake of falsely adding value for trading purposes. However it works, someone still has to leave feedback.

JMO:

The value difference between ExMT, NM, and NM+ on a modern $2 insert is immaterial. If you're (general you, not directed at anyone in particular) going to bicker over that, then I politely suggest you need to find something better to do with your time. For that reason, then yes, for 95% of 'for trade' cards it's perfectly fine to estimate an average grade of NM or so.

Like others have said, when it comes to individual high value or vintage cards, then yes I agree going card by individual card and assigning a grade (even just a 'best guess') is crucial. But for the most part, common base and low end inserts can be bulk assigned an average grade without any trouble IMO.
