They don't mention the tyre pressures. You can run a tubbie at a much higher pressure than a clincher.

In a tiny font:    Roll performance based on 85kg system weight at 7,5 bar. Lower values are better.  7.5 for tubular might be low.  7.5 for tubeless might be high.

Higher pressures only matter for rolling resistance on billiard-smooth surfaces.  Good tracks, good tar roads.  Too high pressure hurts on rough surfaces, because the wheel and bike bounce too much.  Half your power goes towards ramping, rather than rolling.

What's your road surface like?

I think in terms of real speed, there is actually very little difference betrween clinchers & tubbies. Cruxpearl sent me a link the other day to a guy claiming that a drum test, such as Continental's lab, exaggerates the rolling resistance of tubbies.

Very interesting...
