Rating changes

The new way of guests giving review scores is terrible.  We have several scores where the guest has given us 10 for each line item such as staff, location , comfort etc and then given a general score of '7'.  This could be just because the person doesn't ever give a perfect score but reflects detrimentally towards our overall rating.  Whilst the old scoring system was not perfect it gave a better overall value for the property.  

Does anyone else have the same frustration with the new changes?
