GAO sustained a protest recently where an agency had given higher past performance scores to a proposal with two relevant examples of past performance than a proposal with five relevant examples.
In Patricio Enterprises, Inc., B-412740 et al. (Comp. Gen. May 26, 2016), GAO said that an agency cannot mechanically apply an evaluation formula that produces an unreasonable result, such as allowing a proposal with fewer examples of relevant past performance to somehow earn a higher score than a proposal with more examples.
