I do not know the formula they use to rate HP, but I can tell you one thing.
2010 Kawasaki 29 HP V-Twin Professional vs. 2014 Kawasaki 31 HP V-Twin Professional the power is like daylight and dark.
The 31 HP " 2 more HP than what I had" has so much more power it is not funny, so yes there must have been some lying going on in 2010 or the 2014 engine is way underrated.
Anyway I have a JD Z960R with the 31 HP Kawasaki engine on it and this machine mows like a beast with zero issues with being underpowered.

Now if you want the 72" deck the Z970R has a 35 HP engine, so I could just imagine how strong it is mowing. I did start one and drive it around the dealership parking lot today and wow the power it seemed to have while just driving it around the dealership that unit was super strong.
