If I were to scale down to 5V then each of the 30 values would be associated with a .16V=5V/30 range
With this new smaller range, I feel like there is not enough room for error and I could end up reading 'value 24' when in fact 'value 25' was physically present. Is .16V plenty of 'buffer' or am I correct in giving each value a bigger voltage range?

Usually the 'brilliant' idea is nothing of the sort, the entire premise is wrong, and the method of trying to implement it is completely wrong. But as we're all completely in the dark we don't find this out until the thread is many pages long.
This wastes bandwidth, and everyones time - so if you want help you need to provide details! - or risk the thread being locked or deleted!.

I have no problem with being told I am being too vague and that more info is needed -- I do however have a problem with my ideas being referred to as 'the next big thing', 'far form brilliant', 'the premise is wrong', and the 'implementation is wrong'... You can argue that you are not talking about my ideas specifically but there is no question that it is inferred.
