also re: top ten, if meet results include non-USMS swimmers and those meet results are added to the current top times, when the top ten is published, the non-USMS swimmers are removed.
for example, if a :canada: master would come to a meet south of the border (ie here in the states :) ), they would probably be in the current top times, but wouldn't count in the final top ten times. unless they were registered with USMS. but i don't think you can register with both organizations...
