Because that's the standard they set. Did B/S cross that threshold? No. If they did, they should get it. That's why they have record. You can break record, you just can't be given a record. They are given record scores here.
Uhm, I believe that there was new ISU rules and guidance on Program Component Scoring in the last two seasons.
If if you feel compelled to establish a threshold benchmark (which IMO is not appropriate), you might wish to figure out what Davis and White's PCS would translate to under current norms.
