I completed the Basic Fitness Training Assistant (BFTA) Course in 2004. If anyone cares to know the particulars, imagine PT all day, every day, for about 2 weeks. It SUCKED!, but it was a damn good course, and recommend it to any JNCO or SNCO out there that wants to know the DEFINITIVE procedures for Physical Training and the CF Standards. as a NON PSP, BFTA qual soldier, I and other pers who were qualified were regularly called upon by RMC to assist in carrying out Express Testing for RMC Students.
The subject of "Fitness Standards" came up during one of the few "non-PT classroom lectures", and I can tell you that there is only ONE standard for the CF. As per the Fit Vol, the Battle Fitness Test in THE test for the CF....HOWEVER, the CF Express w/20MSR was adopted as an alternative as it was deemed capable of determining whether or not a person COULD successfully complete the BFT, for use in areas and by Units that were unable to carry out the BFT.
I am sure that there are people on this board that might disagree, but that is almost verbatim what the Instructors passed on to us, and if memory serves (which, at my age sometimes it doesn't), he even showed us the reference.
