What is IMR and IMX?

TYS awards certfiticates each season based on USA Swimmings IMX and IMR power points. Below is a description of those awards:

IMX stands for IM Extreme and IMR stands for IM Ready.  During each season whenever you swim an event the time is registered on the USA swimming web site.  This events must be swum at a USA Sanctioned swim meet. Different times score different “power points”.  The faster the time the higher the power points are for each swimmer.  For each event (distance and stroke) swimmers are ranked locally and nationally depending on these power point scores.
