Well done for getting over 20 knots for 10s average so early, it took me a lot longer but Poole Harbour is a bit gustier and bouncier than Portland (thats my excuse anyway).
Watching Jordy's video helped me a lot when trying to go faster, its all in the harness and hips. It took me quite a long time to get the amount I had to move finely tuned and to read the gusts in Poole Harbour.
Also, comparing my AFS foil to the Redwing 1400, its a lot thinner, nearly half iirc. Is the 1000 wing the same thickness as the 1400?
Thick wings has a similar affect as thick fins, lots of lift but more drag.
