SAW has 13 (maybe 14 , can't remember) blocks I believe:
Two Load > Speech > Lift 1 > Just before base of lift > Lift 2 > MCBR > Two brakes > two waiting > two offload.
Stealth could never run three trains because of it's speed and having 4 blocks, the blocks that would start off occupied are Load, Offload + Waiting - By the time the train has got to the end of Launch Block the Offload train wouldn't of made it to Load therefore Waiting would still be occupied causing the ride to E-stop itself before the end of the launch track. The system on Stealth recognises Launch to cover from the start of the launch track to the end of the bunny hop, Which is fair enough
