I've seemed to notice recently the dispatch percentage has gone up significantly, and is now at 12.28% for 7 days and 12.57% for 14 days, maybe this is in a good direction and there's more staff for building!
Still in Pre-Production though...can only hope it changes soon!
There's so many factors that could mean 14+ day dispatch time. It was at 14% when I got mine within 14 days. I know it's easier said than done, but try not to focus on the % I think you're still looking a 12 day build day at a rough guess.
I'm so eager for it!
