With this becoming the situation, you shouldn't assume a WEAP prediction making use of "set up time = 168 hours" to correlate with the onsite observed problems related with EOID, or "set up time = 0 several hours." Simply because this time variable might be manipulated, it is usually recommended to complete multiple WEAPs associated with EOID (t=0 hours) and various time increments pertinent to the particular task desires.
