The E-FIT, Pro-fit, and similar systems used in the UK have been subjected to a number of formal academic examinations. In these studies, volunteers were able to identify the person in the composite about 20% of the time if the composite was prepared immediately after viewing the subject. However,

The widespread use of the original E-FIT approach is gradually being superseded by a new version of the program called EFIT-V. EFIT-V is a full-colour, hybrid system that offers increased flexibility and speed, allowing the face to be constructed using both evolutionary and systematic construction
51:
The system first appeared in the late 1980s, programmed by John
Platten and has since been progressively refined by Platten and latterly by Dr Matthew Maylin. E-FIT has developed a reputation as a highly reliable and flexible system for feature-based composite construction.

one study found that if witnesses were required to wait two days before constructing a composite, which matches real-life applications more closely, success rates fell to between 3 and 8 per cent.
