      This chart was designed for simplistic "Digital Key Entry" but still allowing for various power equivalents.  For example.:  Digital Key Entry:  444 @ PL-9 will bring a 2 cup container of water & 2 tea bags to a short boil very nicely with a 800 watt microwave. (Reduce time &/or PL with 1000 watt+ microwave ovens.). 
    Because Microwave power can only be full "on" or totally "off" the only way the manufacturers can regulate power is by regulating the effective full "on" cooking time.   The numbers represent percentages of full power for example the #8 is 80% of full power so that the effective full "on" cooking time over 30 seconds would be  0.8 x 30 = 24 seconds "on" and "off" for 6 seconds.  For a minute at 80% it would cook: 24 sec "on" - 6 sec. off, 24 sec on - 6 sec. off for an effective cooking time total of 48 seconds "on".  [BTW the owners manual didn't have this info. in it.  I had to figure it out for myself.]
    One of my favorite items is baked potatoes and I've learned that  8 oz. at 8 minutes at power level #6 bakes one of them just right.  Sometimes I'll have a meal in the oven and get interrupted and by using this chart I can keep it hot without over cooking it by using power level #5 or #4.
