but the fact it went from a possible 18 mths
One word..."mercenary"
Accelerated is in the same booth as DEC, it bypassed any resemblance of a seniority list. Yes, EK will do as they like because they can but you're not going to get a sympathy vote if you call 'unfair' on a missed accelerated command or any other variation of a moving post. Not knocking anyones decision to join as a DEC/Accelerated or whatever planet you think you're on, just don't call foul when it all goes pear shaped.
Back to the brown letter.........not a chance.
