^^ express is from the point of posting, which I've learned is 9-10 days, I'd assume the cheap postage could take anything up to 28.
5 weeks was just the time his took for the entire build process for his bike, he has busy times & not so busy times, he has other things going on & will probably have the odd emergency too, like I said that's from drawing it and getting the ok from you at every stage, cutting the tubes for your geo, getting all the tubes in the jigs making sure everything's straight, building it and painting it, then posting it.
I gave him my geo and I had the frame about 17 days later, I guess I got lucky
