Actually, I think it all gels perfectly including your suggestion, which is correct providing of course that the equipment is functioning correctly.
FWIW, I've been skiing similar terrain for ~20 years on other bindings @ DIN 6.0 and experienced very few inadvertent releases. The shop set these @ 5.5, which is the recommended value for a Type III skier of my height, weight and age (now that I'm well over 50yo).
I had them checked today and everything is adjusted and functioning correctly. Boot sole length is correct and actual measured release forces are within the range they should be @ 5.5.
This supports your recommendation, which is also what the shop tech suggested. When planning to ski serious terrain I'll move them up to 6.0 or even 6.5. This is the equivalent of categorizing myself as a Type III+, which seems appropriate for those circumstances. The risk from a ski coming off (which I just lived through four instances of) is much higher than the risk from one staying on. I'm unlikely to experience a slow, twisting fall in a 40 degree chute, whereas the chance if a serious fall/slide if I lose a ski is virtually 100% - trust me!
P. S. As a featherweight, 58yo gay guy, TGR macho wouldn't be my shtick, lol, but your advice is simply common sense. Binding systems and settings are never perfect. They're mechanical compromises in circumstances far too complexx to model accurately. We each must make the best estimate we can of risks vs, rewards. Thanks for helping make that clear.
