You have to be a bit careful with some of the claims for volume flow and suction. The 92 cfm probably means maximum without any hoses and it would not be surprising if the filter was not on. The 134 inches of water could be the level the water surges to; like you have the sucker running, dip the calibrated pipe into a water bucket and measure the highest point the water reaches as it has some momentum. That fact that it stabilises well below that is ignored.
