Not a big deal, but... Note that higher E-series do not "add" values or "fills in" any values. Many values from lower series are actualy replaced. Some values are only available in a single series, like the 300 resistor in the EasyProg (hey ! back on-topic !! :-) ) that's only available from the E24 series but not in either any lower *or* higher series.
