Which plan is best for me ?

Hi


Today I was just wondering if I should switch over to 'Pay per second' plan from my '0.5 rupee per minute'. I couldn't really figure out which one was better. All I wanted to visualize it to be clear. And so here it is. An application that I made to visualize how the two plans cost with time.


(Refresh the page to see it again).

LEGEND:
Red Line - pay per second ( 0.01 Rupee per second).
Blue Line - 0.5 Rupees per minute.
Green Line - time where the 2 plans cost equal.

ANALYSIS:

As is clear from the graph, after ~200 second (the 4th green line) Red Plan never comes below Blue Plan (except for few seconds). It costs more than Blue Plan after that point and the difference between them only keeps on growing with time.
Before that, Red Plan costs less than the Blue one for most of the time being the best specially between 0-150 seconds (3rd green line).

VERDICT:
If you make calls that generally last for about 200 seconds or less, Plan Red is for you. But if you like to talk for long durations to your pals gossiping about the cricket match or last night party then Plan Red is certainly not for you...Go for Plan Blue.  :D

Duration                             Plan
0-200 s               Pay per second (RED)
>200                   0.5 Rupee per minute (BLUE)


Just in case if someone wants to see the application code :
