I've heard several times on these forums about the "1 in one thousand usual MDC standard for a preliminary test." Unfortunately, there is nothing in the rules that mentions any such standard. Rather, there is only:. . . 1 in one thousand, which is the usual MDC standard for a preliminary test.
(1) The vague opening sentence to rule number 3. "We will consult competent statisticians when an evaluation of the experimental design, is required"; and
(2) Rule number 6. "In all cases, applicant will be required to perform a preliminary test either before an appointed representative, if distance and time dictate that need, or in a location where a member or representative of the JREF staff can attend. This preliminary test is to determine if the applicant is likely to perform as promised during a formal test, using the agreed-upon protocol. To date, no applicant has passed the preliminary test, and this has eliminated the need for formal testing in those cases. There is no limit on the number of times an applicant may re-apply, but re-application can take place only after 12 months have elapsed since the completion of the preliminary test."

So what, exactly, is required to pass the preliminary test?
