Whatever developments you speak of would need to be applied to both profiles equally, and there is therefore nothing so far to indicate that there is any magic to decompression. Are you saying that we can expect a theory in the future that will demonstrate that the 50/100 is actually better than 36/80? Do you know, offhand, if this magical theory takes into account the fact that breaks are being taken from O2? There wouldn't be any published findings by any chance?

Yes, and I'm sure that the majority of divers out there won't mind blowing off 25% to 33% of their shallow water decompression.
