This is not directly related to your question, but I did a simple
study of which pricing plan is the most cost-effective for accessing
CIS. These calculations are based on the following (2/6/94) rates:
Stardard Plan Alternate Plan
————————————————–
Monthly Fee : $ 8.95/month $ 2.50/month
————————————————–
300 baud: $ 4.80/hour $ 6.30/hour
1200,2400 baud: $ 4.80/hour $ 12.80/hour
9600,14400 baud: $ 9.60/hour $ 22.80/hour
————————————————–
The formula for when the Standard Plan costs less than the Alternative
Plan is simple:
nr + m < nR + M
Where n = number of hours online/month.
r = hourly rate for standard plan.
R = hourly rate for alternative plan.
m = monthly fee for standard plan.
M = monthly fee for alternative plan.
Solving for n we get: n > (m-M)/(R-r)
This tells us that the standard pricing plan is more cost effective
when the hours on-line (n) exceeds . . .
n Hrs/Month or n Min/Week
————————————————–
300 baud: 4.3 Hrs/M or 65 Min/Wk
1200,2400 baud: 0.80625 Hrs/M or 13 Min/Wk
9600,14400 baud: 0.48864 Hrs/M or 8 Min/Wk
————————————————–
This study is only valid for time spent in "Extended Services", such
as the ASOFT forum, under Standard Plan. Also, keep in mind that any
session has a minimum of 1 min charge in either plan.
BTW: M. G., make sure you are under the Standard pricing plan. The
$23/hr. rate sounds suspiciously like the Alternative rate for 14.4
Kbps. If you are not sure, try GO BILLING. Also, there is an $8.70
/ Hour surcharge for an 800 connection — your phone company probably
will not charge you that much for long distance. See GO RATES under
Communications Surcharges.
