LB – from what Iacisrmma here wrote, you would only light an extra candle if you FORGET to light. This is an extremely rare occurence and probably the reason NCB has rarely seen this observed.
I seem to remember learning something like this as well. B”n, I will try to look it up when I have a chance.
As far as bt’s are concerned, I could hear where if someone is just starting to light, it is possible that they could forget a lot. But that would mean that they haven’t really started lighting regularly yet, so it’s hard for me to imagine they would get a penalty for “forgetting” until they are at the stage that they really light regularly and the “forgetting” was an unusual occurrence.
