In 2001 I had 3 top ten times thrown out from the Northwest Zone meet because the pool was 2 cm. short. I accepted it albeit grudgingly. I thought our new rules precluded this from happening again! On Oct. 4,2003 in Tempe I was ecstatic after my 100 M Br. when I went my best time in 5 yr. & broke the NW Zone record. The next day it was announced the bulk head wasn't mounted properly & lanes 1,2,& 3 were 1 cm. short so swims from those lanes didn't count for records or TT.The officials were polite & let the affected people swim the events over.That was the best mitigation they could do. In the reswim I did well just missing the Zone record,close but no cigar. Can't something be done to truly prevent this in the future!!
