I really do not care about slowing down that muck, what I want is to the exhaust brake to do a good job of holding the speed i want going down a hill or mountain. At 24,500 combined with the 3.42 gears it does good job in 4th gear and in 3rd gear on curvy hills like Cabbage Patch. Despite what 4x4ord thinks, the Cummins alone does very little at holding back speed on hills. That's my story, as I do own one!

I realize you want the exhaust brake to hold back on a grade. The purpose of measuring the time it takes to slow the truck down is to calculate the reverse hp that the engine brake generates. If it generates 180 reverse hp at 3000 engine rpm on level ground without a trailer it will generate 180 reverse hp at 3000 engine rpm holding back a 20,000 lb trailer going down a steep grade.
