1. Find the Weighted Average of Calls Carried (WACC) of the current
data.
W xNCC
1 C 1
WACC = ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- -
2. Divide the WACC for each interval by the sum of WACC for all
intervals.
3. Multiply the quotient found in Step 2 by the Expected Calls (EC) to
get the FCC for each intrahour interval.
