I've found that to be true too, the older the egg the easier to peel. I always buy the supply of Easter eggs for the grand kids to color two to three weeks before Easter. I use a similar system to his except after boiling I sightly crack the egg and set it in cold water, refrigerate for a couple hours then peel. Like he said though you will always have that one relenting egg among the bunch. I also do his boiling technique, I see it on food network when they were showing people how to boil a egg that won't produce that green overture on the yolk.
