I know the philosophy on marks is to repeat the concept, but not the actual mark and I do understand it, but...
...when running blinds do you train the same way? I usually put out 3 or so bumpers & re-run if it seems I had to work hard against a certain factor. The result on the repeats is much like a cheating single-"Oh ok! I get it now" & the line is good. But does the dog really learn anything from that?? i.e.-is he remembering the casts that kept him on line (not in a literal sense, but I think you know what I mean) or is he just going straight (& fighting factors) because that's what he's been taught & frankly-he knows where the bumper is?
If anyone understands my question I'd appreciate feedback!
