THE YOUNG AVAILABLE DAILY WITHDRAWAL QUANTITY FORMULA

 

%YMAC = Current Inventory/YMAC

 

------------------------------

%YMDWQ Calculation (1,2,3)

 

If the %YMAC is > or = to 60.12%

then set the %YMDWQ = to 100%

 

------------------------------------------

 

If the %YMAC is < 60.12% and > or = to 15%

then

%YMDWQ = (-15.3150) + (%YMAC * 2.6838) -

(%YMAC^2 * 0.0786) + (%YMAC^3 * 0.0011)

 

------------------------------------

If the %YMAC is < 15% and > 0%

then set %YMDWQ = to 11%

 

------------------------------------

If the %YMAC is < or = to 0%

then set the %YMDWQ = to 0%

 

------------------------------------

YADWQ Calculation

 

YADWQ = (%YMDWQ/100) * YMDWQ

Rounded to the nearest whole Dekatherm (an integer)

-----------------------

 

NOTE: In the context of this formula, the %YMAC and %YMDWQ values are

taken as whole numbers, and not as decimal only numbers (i.e., use

40.0 not 0.40 or use 36.1234 not 0.361234).

 

NOTE: The coefficients are entered with four decimal places, and the table

is calculated with four decimal places, and then rounded for display

purposes.

 

NOTE: All calculations are initially performed utilizing four decimal

places. The final YADWQ, however, is rounded to the nearest whole

number.
