You will notice with E12 values that each succeeding value falls within the plus/minus 10% of the previous values.
This stems from the real old days when resistances were stated as within 20% tolerance(accuracy).
Later values of plus/minus 5% tolerance led to the E24 range of resistance.
Quite common today are 2% tolerance metal films types but for general purpose use we tend to stick to E12 values of resistance in either 1%,2%or 5% tolerance.
Cost is the determining factor and many retailers now stock the 2% range of resistance as a standard to accommodate stocking levels and also at reasonably low cost.
