Pacing will alter significantly as testing continues. Firstly the train literally crawled over the crest of the lift hill, in a couple of weeks it will be going significantly quicker over the top as Mack lifts are normally fast. This won’t dramatically alter the speed at the bottom (probably only a couple of mph) but that will mean a significant amount of additional kinetic energy is being carried by the train. Secondly the friction will reduce as the ride beds in and warms up so the speed will be maintained throughout the layout. This will probably mean more airtime but less hang time
