At 3000 'unique' counts, I don't worry about it anymore. However, I aways give feedback on any type of transaction, which in my case, are 99.9% to buyers. I leave feedback because it's the right thing to do, not to bolster somebody's numbers. Your feedback will grow over time, and high count or low, you'll still have customers buying from you. So, as I said earlier. Don't worry about it. Concentrate on quality and service, and you'll get your numbers.
