You nailed it, Cal.
Dynos measure torque, and than calculate horsepower.
DynoJet has an outstanding marketing plan and has saturated the market with their products. Some tuners consider their caculations to be optimistic, therefore discount single runs as irrelevant.
Multiple runs, performed by a certified operator, in a controlled environment, using a machine that is calibration current are necessary for relevant data.
LOL at the quarters.
I am guessing that this was a feeby since they witheld the pertinent data. More of that enticing marketing stuff.
