I guess it's a very subjective feeling : I tend to simplify the more I can and I need things to be almost compatible with a 5 year old kid (which is the kind of intelligence I have when it comes to analysis), and I always need to rely on physical oriented things, such as the fingers on my hand : beyond that I'm a little lost ;-) But I completely understand, and it's technically very easy : in a spreadsheet, everyone can select the values he wants for data validation. So it can be from 1 to anything we need. What do you think of the idea of customizable criteria (tension, romance, emotion, ECG, etc) ?
