I never got posing or showing in general once it diverges from the functional use of the animal. You are describing exactly why I gave up on showing anything. Total burnout on the subjective and irrational reasons given by judges.
I can only imagine that it is better to breed to the philosophical intent of the shape--broader well filled loins and hind legs are better for meat production, and so I would aim for that, and posing is dependant on cooperative temperament partly, and that is also something you could breed for.
Sorry, just want to express my commiseration for your frustration, I don't really have any solutions.
So I have had different experiences with this. Posing is part art and part science, and it needs to be done in person, and needs to be done correctly. Rabbits can be trained to pose, but there should be no "forcing." The point is not to fake anyone out; the point is to put the rabbit in a position that allows assessment of quality. I know some judges that are absolutely fantastic at getting a rabbit to show itself to its best advantage, but I've found that a few judges and very many breeders do not know how to pose an animal correctly. And some people are just better at handling animals than others.
Some rabbits push against you (Rex and Mini Rex, I'm looking at you!), but with experience for the handler and training for the rabbit, that can be dealt with. Others fight being posed, but even that can be very useful in the assessment of the particular animal, and in learning how to judge rabbits, because a rabbit with structural defects is usually very uncomfortable in the pose proper to the breed, thus will fight it. Form really has to follow function, certainly in meat breeds, but it holds true even in the fancy breeds like Holland Lops or Brittannia Petites.
Posing is not simply visual assessment. It involves direct physical interaction with the rabbit, during which you get to see the rabbit move, and have the chance to
feel muscle tone, thickness of shoulders and loin and hind legs, to note how far down the leg the meat goes, to tell if there's a hesitation between the base of the neck and the beginning of the back, and many other details you might not be able to judge just by looking. Assessment is not just looking at a profile of a rabbit; it necessarily involves touching the rabbit, and getting a top view, a hind view, and a view of the underside of the rabbit, which you cannot get from a photo of a rabbit placed bunched-up on a table with a human hand over its head.
Having said that, after you've handled and posed enough rabbits, you can start to develop an eye that allows you to quickly perceive that a rabbit has a hollow loin, a narrow chest, or is pinched in the hindquarters, for example, even when the rabbit is sitting in the cage (I think of this as "cage presence"). Once you know what you're looking at, you can pick out many of those details without touching the rabbit, and those features can no longer be hidden from you by improper posing. You can also pick out instances in which a breeder/handler is either inexperienced or is trying to conceal something by posing the rabbit incorrectly (often called "overposing" or "underposing").
You can tell that a rabbit has an early peak and a hollow loin whether it's bunched up or sitting "relaxed."
You can tell that a rabbit is pinched and slightly hollow whether it's overposed or underposed.
In meat rabbit breeds, a good show rabbit
is a good meat rabbit. However, given that it's a human endeavor, there are great meat rabbit judges and there are those who have other priorities; there are judges that really study the standard, including the rubrics for meat classes, and those that don't; there are judges with a wealth of years of experience and those with very little (and sometimes don't seem interested in getting any more). Just like searching out an "expert" in any other field, it pays to find a really good mentor who actually knows what he or she is doing, and will give you a chance to learn, hands-on.
I agree with
@eco2pia that examining your rabbits on the hoof and then parted out is a great way to refine your ability to judge quality. But I have learned
so much more than I ever could have picked out by myself, by watching judges (both good and not-so-good) and from scribing at shows, especially for the meat classes. I see things now that were completely invisible to me before. Do I agree with every judge's assessments or opinions? Not by a long shot. But I listen to what the judges say, put it together with my own experiences and observations, and then make up my own mind. It's been a very successful approach for me, as evidenced both by show winnings and by incredible carcasses.
IMHO,
photos of type are mostly, though not completely, useless. Putting your hands on the rabbit is key. Although they did have one ARBA Convention on Zoom (in 2020, I think), that's one of several reasons that "virtual shows" did not take off after the Covid restrictions were lifted. Many or even most breeders agree that it's nearly impossible to fully assess or compare rabbits remotely, in either photos or videos.
