Guild Wars 2

Tl:dr Windborn dagger doesn’t seem to be providing any speed boost (or at least this speed boost is no applied in the heart of the mists between the two portals)

I didn’t see another post on this so I figured I would post here.
While testing to determine what speed buffs stacked in the new patch I measured the following speeds. (All speeds are averaged, N=2, and normalized where the duration to travel from point A to B is equal to 1)

1.00 No sig
0.93 5 Points in Air
0.82 Signet of Air
0.82 Signet of Air + Windborn double dagger + Air 5 + One with air
0.81 Signet of Air + Windborn double dagger + Air 5 + One with air
0.93 5 Air + Windborn off dagger
0.92 5 Air + Windborn Main Dagger
0.99 Winborn Double Dagger

This data shows that three things:
1: It appears that Windborn dagger doesn’t work
2: It appears that no movement bonus stack after the patch (As I believe was true before)
3: One with the wind isn’t effective until you’ve been attuned with air for 30 seconds.

Can anyone else confirm this data or could someone tell me what I’m doing wrong when collecting it?

Thank you,
