Suunto Computer's

Yes, but they are different limits. If all other risk factors are held constant, the younger, fitter diver can safely dive closer to an objective (table, computer) limit. Although I keep pretty fit, 50 is still 50 in many respects, so I take a dive or two off in the middle of a dive week these days.

I don't find my Suunto D9 (set to 50% RGBM) unduly limiting on a liveaboard trip. I have never had any problems with pairing or transmission lapses in ~4 years and ~300 dives. The original battery is still going strong.

I think you may have missed my point. In the real world, those "other risk factors" you refer to cannot be kept constant. They are called "variables" for a reason and individual susceptibility varies greatly. That is why conservatism is required in decompression algorithms - to keep you from getting bent.
