Good SPSM practice is again followed by keeping the file documentation up
to date.

The CTCPC parameter is increased by ten dollars to $1212 in this run.

This completes the setting of the parameters required for our FACTC2 run and
we now proceed to the execution phase.

The increase in consumable income shown here will be slightly different than
the corresponding figure in the output table file. This disagreement is smaller
than rounding error and is caused by slightly different means of applying
weights to the estimates.
The following is a listing of the first table in the FACTC2.TBL file created by the SPSM
run.

+--------------------------------+---------+
|Base Consumable Income (M)
| 365958.4|
|Variant Consumable Income (M) | 366016.8|
|Change in Consumable Income (M) | 58.3|
+--------------------------------+---------+
The table reveals that consumable income increased by $58.3 million over the
FACTC1 run. Since the CTCPC parameter was increased by $10, this means that
each $1 increase in CTCPC results in an increase of $5.83 million in consumable
income. Thus, to eliminate the $1724.4 million overshoot of the FACTC1 run, we
should decrease CTCPC by 1724.4/5.83 = 295.78 dollars. Since the FACTC1 run had
CTCPC set at $1202, our new estimate for CTCPC (for the next run, FACTC3) should be
$906.25 ($1202 less $295.78).
