All WCS points are equal - a collection of WCS points from varsity sports carries no more weight than the same number of WCS points from non-athletic activities. The most WCS points wins - there is no committee putting the thumb on the scale in favor of varsity athletes (except for recruited athletes).
It is easy to confuse correlation with causation. USMA does not select varsity athletes; varsity athletes select USMA. West Point is a very physical environment and the overwhelming majority of those seeking appointment are involved in physical activities - the applicant pool is not a uniform distribution. There are far fewer applicants with no varsity sports than there are applicants with varsity sports. Adding the additional hurdle of passing the CFA explains the very high percentage of appointees with varsity sports.
