Firstly, why are you doing your track intervals in Hoka Speedgoats? They are a trail running shoe, and a fairly robust one at that.
Secondly, there would be considerable difference between the shoe models you've mentioned. In a study measuring running economy, the Vaporflys were said to have roughly 3.5% benefit, whereas the Brooks and Hoka super shoe models were said to have no measurable benefit over a pair of traditional racing flats (I believe they used the Asics Hyperspeed as a control).
Thirdly, of course there's a speed advantage over the shoes you've listed, as they aren't even racing flats. Therefore, we aren't going to be able to settle on a time conversion, because the only people that do track workouts in daily trainers are: old dudes with chronic calf injuries; and hobby joggers. When people are doing conversions, they're comparing traditional racing flats to the Vaporfly/Alphafly.
