Frame weight is 1440g which is 60g more than advertised. Of course, advertised weight might have been for the raw frame or without the derailleur hanger. Who knows? The fork was spot on at 520g.
My current plan is to remove the derailleur cable stops and rear brake cable stops, then drill the necessary holes for internal di2 routing and internal rear brake cable routing. I'll then sandblast the frame and, perhaps, polish it. I suspect all that could drop another couple hundred grams. It looks like I'll only need to drill one hole on the downtube, one on the seat tube, and one on the chainstay for the di2. There are holes through the b/b shell into each of those frame tubes already. The trick will be the brake cable routing. Finding the necessary grommets for the di2 wires is easy, but sourcing grommets/guides for an internal brake cable looks a bit tougher. So far I have only found these:
Hopefully, with the Alpha Q fork, I can get the combined frame/fork weight down to around 1500 grams. But first I have to find someone with a little more skill than I possess to grind off the cable stops and drill the required holes. I don't want to do it myself as I lack the proper tools.
