I saw a post (Flashback Bob?) where it was observed that new lump will bring the BGE up to the desired temperature faster than using old, previously used lump. This is directly contrary to my own experience.
In all of my eggs the old stuff will heat up so fast I barely have time to go grab a beer, I mean go help my wife prep the meal. Also, with the old lump there is almost a non-existent wait for the VOC's to clear. I assume this is because once consumed they do not regenerate in the lump.
So I am curious what others have observed: when you light your egg does new lump get to temp at a faster or a slower rate than used lump?
