The Yale, UW and WashU forms are of questionable utility in my mind. While many LoR writers genuinely have known the applicant for years, most will have known the applicant for a few weeks or months at best. The comparisons, while providing candid information, are likely to be filled out be secretaries as the burden grows (ie there are 3 programs demanding this now, but when there are 10 from top-tier programs, what will we do?)
It seems to me that the initial burden is on the student but progressively this responsibility will shift to that of the evaluator - indeed, to some of the program directors that are instituting these requirements. Once a threshold is reached, these forms will either become useless (evaluators will not be the ones filling them out) or there will be a move towards standardization. In order for the latter to occur, the Ortho PDs need to work with ERAS or establish a separate LoR/eval system.
My two cents on the matter.
