Most of the performance data means nothing.
The data that matters is the vac/airflow figures under load doing a cleaning stroke.
As far as I know nobody measures that. They measure free airflow and vac under nil airflow.
The real answer is somewhere in between.

the nice thing about the bane was the fresh tank was connected into the van cooling system so as you drove to the first job it heated up the water, it also had a heating element fitted so you could heat the water over night.

the tank was also insulated to keep the water hot.

They were a good design and well built, the problem was the lack of power.
