Just browsing the net (to avoid working) I came across this on the UK Tang Soo Do website ...
Grading 1st Gup to 1st Dan
Promotional Requirements for 1st to1st Dan (Midnight Blue Belt):
Candidates’ Basic Requirements.
To qualify for grading, candidates must have attended class at an officially recognised ITSDF club for a period of not less than one hundred and twenty one-hour sessions prior to the grading.
120 hours from scratch to 1st Dan ...

OK I know it's easy to be elitist about these things but that does seem to be an incredibly short minimum period. Even McDojos require more (and a large cheque of course

)!! Even just doing 2 hours a week you could theoretically pass Shodan in 15 months!!
Apart from buying one off EBay is anyone aware of a shorter way to a Dan grade?
