I happy to see someone trying.
To have any chance of the method working, you first have to adapt the ranges to your taste!
Just because for me "boring" is in the 0-20 range, obviously doesn't mean it's in the same range for you. So you might have to stretch "boring" up to 55, relocate "neutral" to 55-60 and shorten "enjoyable" somewhat ... just to give you an idea.
So basically, you need to redefine ALL the numeric ranges (i.e. stretch/shorten/relocate them accordingly).
You can obviously rename the parameters as well.
Once you have adjusted the scores to your liking, you can mark the applicable cells (as you have done).
By default (normally) entire ranges should be marked. This should be used most of the time. Like this:
But if you have a very precise idea where the marking should be within a broader range, you can also mark only parts of a broader range, like this:
(The disadvantage is, that if you mark, say, only a cell in the 65 column, the neighbouring columns don't get an upvote).
If your feelings are right "between" two cells, or if the film has ups and downs, you can mark two bordering cells like this:
If you are unsure or torn between two adjacent ranges, or the film has huge ups and downs, you can mark two adjacent ranges like this:
When you are ready, it's time to count.
I have done this with the example you provided in your screenshot. The result is this:
In this case "65" is the clear winner.
So according to MY voting taste
, your film would get a 65.
As already mentioned, you first need to adapt the ranges so that you would get the appropriate score according to your voting style (what the numbers mean to you). Then the final number should come out about right.
