Can you actually list all 40 readings? It matters because if 39 of them measure between 1350-1360 Ohm and 1 reads 1310 Ohm, then

1360 * 0.97 = 1319 Ohm. OR 1310 * 1.03 = 1349 Ohm.

How the 3% guideline came about by PlainBill.

edit: We have had cases where the measurement was off by as little as 5 Ohms to cause "2 seconds to black".
