wanna_code_perl:

I don't have enough detail to know what you're finding tedious & repetitive. If you mean setting up the script and all the code around the simple calculations, then create a "boilerplate" template where you've got most of it set up, and just add a subroutine at the end to do the work.

If you mean all the intermediate chunks of calculations, you can write simple subroutines to encapsulate much of it. If you gave us an example of what you're finding to be the tedious and repetitive parts, I'm sure someone may be able to come up with an idea to simplify things.
