Evolutionary systems show a marked improvement in accuracy. In academic trials, research on a fairly-recent version of the EvoFIT system has shown correct naming levels of about 30% after a 2-day delay (see Frowd et al., 2010). Using more-recent construction techniques, the performance increased to 45% correct naming (Frowd et al., 2012). Using the very latest system, interview and enhancement techniques, naming of an EvoFIT composite is 74% correct (Frowd et al., 2013). Appropriately, the system does appear to behave more like a face recognition than a face recall system (Frowd et al., 2011) Accompanying the development of EvoFIT have been new approaches in the type of interview administered to eyewitnesses prior to face construction (e.g. Frowd et al., 2012). Similarly in extensive field use EFIT-V has shown a 40% naming rate over an 18-month period with 1000 interviews. The EvoFIT system has been similarly evaluated in formal police field-trials. These evaluations have reported a much higher naming rate for EvoFIT composites but, using the latest interview techniques, a suspect arrest rate of 60%. This latest police field trial has also indicated that an EvoFIT directly leads to the arrest of a suspect and then a conviction in 29% of cases.
