Okay. Since I have had no replies I will add some details as to what I would mean.
A random score is produced between a range of numbers that can be a undetermined amount.
The number range at one point could be 10 in size (30~40) or it could be 20 in size (40~60) the number range is unknown and is susceptible to change.
A uniform value needs to be calculated for each random score inside that range or any range that always gives a 0~1 value no matter the range numbers or the score.
The higher the score the larger the value needs to be in the 0~1 range.
To me this is the same as normalisation, perhaps I am using the wrong word for this, however getting a unit length of 1 for no matter what the range is to me would be just that.
