Does anyone who knows more about the algorithm than I do see how this can produce a stop deeper than the max depth after clearing the diver on his first dive? #----------------------------------------------------# Roger Carlson H 310-376-4437 Somewhere off Hermosa Beach, CA W 310-813-0858 Roger_Carlson@at*.sp*.tr*.co* F 310-812-1363 #----------------------------------------------------#
