Hello Mchammer,
The records are tumbling in all sorts of fields. Human endeavor. Motorsport. Technology.
The increments, however, are getting smaller. Records are now often set in thousandths of a seconds as opposed to mere seconds.
Without the aid of drugs and dubious breeding techniques, the outright record for a 100m Mens sprint is a theoretical 9.654 seconds.
Please also bear in mind that around 89.64% of statistics are made up on the spur of the moment! :-)
Regards
Z
