Thanks for the comments and suggestions, they have given me a bit of input regarding the new meter that i am building. The project is progressing quite nicely and i hope to have the first version out over the weekend some time. The indicator will be of the same quality and value as the ones that are currently for "sale", and also the meter that I am building will be adjustable so that the user will be able to input quite complex systems and get a good % or feed back regarding the inputs, I will supply it with a basic system, that will be profitable if followed. Any further suggestion is welcome.
