I used to be a very active TRS but moved and started law school. I accumulated several late shipments before stopping selling from Feb-May, but started again in June at a low volume. With my old volume it put me around 2%. Now I sell 3-5 items a month a week instead of 60 and those late shipments have pushed my late shipment rate up to 20%. So... what happens?
I've been on time with 100% of the stuff I've shipped since coming back, but thats only about 20 items, so my rate has actually been climbing (from 10% to 24% then back to 20%) as months of 60 items at 2% late roll off. I've been above the 7% "we may follow up" level since I resumed selling and my sales seem OK.
