i have a feeling your not understanding my view point...either that or your just digging in your heels and refuse to see any validity in a non MMA view.
so instead of wasting my time trying to convince you of something, i will turn it over to you. you tell me....how can i practice stand up techniques like irimi nage or any of the wrist break type techniques (and i mean wrist breaks, because i do not believe pain compliance works on a standing opponent) how should i be practicing these without damage to my partner and without going so slow that they are not realistic?? techniques need to be done fast and powerful with a full range of motion but without injury.
I'll drop in a few thoughts from a less antagonistic viewpoint, just for the sake of sharing ideas (I don't assume you need this input, but maybe it can be helpful).
With techniques where going for the fall is a safety measure, I work hard to give good feedback after the fall. Sometimes I'll say, "I wouldn't have had to fall to escape that one." Other times, "Wow, that one had me locked before I could even change directions." That spoken feedback can help your partners some, since they aren't getting as much of the failure feedback. I sometimes ask my uke how it felt, if I don't think they're providing good enough verbal feedback. If I never get negative feedback, I start getting purposely sloppy, to make sure they are notice and tell me.
Where I can safely (for both of us) do so, I'll even stymie a technique that fails early enough for me to recognize it before starting toward the fall. I've had experienced uke do the same for me. And when I'm really on, I can sometimes delay going for the fall later than is normal, to ensure I'm not giving in too easily.
Slower practice can also help. For an experienced uke, a 25% slowdown can give them enough time to recognize the need to fall (or the lack of that need) without losing a reasonably realistic momentum flow. Of course, even that 25% slowdown will give me an unnatural amount of ability to read attacks and respond to them, so that has to be taken into account.
