I gave you both of those things. I allowed for an 80mph raven that never rests, and a 160 mph dragon. I even took an hour off Gendry's sprint for you. Even with those gifts we are looking at a MINMUM of 34 hours, not "up to 20 or 34". What I argued against was that you have Westerose being 1/3rd the size that GRRM says it is and that Dragonstone is less than half way to the southern tip, when its almost 2/3rds of the way.

My apologies to the dead horse.
There's hundreds of westeros maps out there. All with difference interpretations of distances between points.
What you're referencing is one version of the westeros map. I literally looked at one map and the fact that it was overlayed parts of europes to ball park my distances. Maybe they aren't accurate in your eyes, so be it.
Here is an article that states it is between 24-36 hours. Using similar assumptions as us. The biggest really is they assume 50mph or a raven however they believe the dragons can go several hundred MPH not just 150. I had no idea people had calculated this out there and I was making broad assumptions in the moment on what I knew and I came up with 20 hours. So I'm 4 hours low on what some other source finds reasonable or 14 hours off from what you've calculated. The point once again is that it doesn't take days/weeeks but maybe a day or day and half

Quote from Director Alan Taylor
“We’ve got Gendry running back, ravens flying a certain distance, dragons having to fly back a certain distance…In terms of the emotional experience, [Jon and company] sort of spent one dark night on the island in terms of storytelling moments. We tried to hedge it a little bit with the eternal twilight up there north of The Wall. I think there was some effort to fudge the timeline a little bit by not declaring exactly how long we were there. I think that worked for some people, for other people it didn’t. They seemed to be very concerned about how fast a raven can fly but there’s a thing called plausible impossibilities, which is what you try to achieve, rather than impossible plausibilities.”
