That's exactly what I'm talking about. We're talking about inexperienced honers right? So that's a good example of something that might drive a new honer nuts. If they breadknifed they'd have a known starting condition. It really doesn't matter how much extra work it might involve or if they breaknifed a perfectly good bevel. What's important is that they are starting with a known condition.
I wouldn't recommend it unless it was a damaged edge but I wouldn't rule it out because it isn't "right" to do it that way either. All's fair in love and in sharpening.
