"For 2005, the total timeout parameter will be adjusted to 10 seconds for all Sportsman categories, down from the 15 seconds the system had been set the previous years of the AutoStart system."
" As part of the system, courtesy staging is in effect for Super Stock, Stock, Super Comp, Super Gas, and Super Street. Both contestants must activate their pre-stage lights before either may advance into the stage beams (this is considered a courtesy rule and the starter has the option of backing out both drivers and re-staging to assure a proper start)."
