The RTH temperature used to be 5c. No idea when it went up to 6c, or why.... But they have had it stall / valley a few times, so can possibly connect the dots.Out of interest, does anyone know why those temperature limits might be in place? I thought that most coasters/parks were closed in European climates over winter for commercial reasons, not operating reasons.
Maybe risk of valleying if they run too slowly...? Can't think of anything else!
