You'll want a 5/5 haste samba DNC to test haste samba, not just a random DNC with access to the JA.
blah nvm
Just did a quick test before bedtime... I'm almost certain now that haste samba stacks with magical haste. I want to redo this with higher delay weapons (relic stage 1, or a 2-hander with Hasso) and haste hands instead of ring to make the measurements easier. Hate having to reset TP to keep shinobi ring active, whilst controlling a stopwatch.
Main: 75 NIN/SCH - hushed dagger (188 dly), Xiphos (228 dly) - no added DW or DA gear
W. Turban 50/1024 haste
Shinobi ring active 4%
Speed belt 61/1024
Byakko's haidate 5%
Usukane sune-ate 2%
515 skill BRD marches 211/1024
haste spell 150/1024
Total: 58% haste, or 0.42 * base delay
Time between 1st and 11th rounds: 20.90s, 20.66s
Observed delay for both hands:
2.078s * 60 = 124.7
Theoretical delay with 58% haste, 30% passive DW:
(188 + 228) * 0.7 * 0.42 = 122.3
Adding fully-merited haste samba (75 DNC/NIN):
Time between 1st and 11th rounds: 16.44s
New delay = 0.42 * 1.644 / 2.078 = 0.332
New haste value = 1 - 0.332 = 66.8% (8.8% higher than before)
Had haste samba reduced delay separate from DW and from haste, the new haste value would have been theoretically 4.2% higher than before. It remains possible that haste samba stacked with DW (resulting in 64% apparent haste), but because haste samba does not reduce TP like DW does, I doubt haste samba combines with DW.
I reckon a hand controlled stopwatch and the effect of network lag after just 10 rounds of animation at 2 seconds a round makes this a pretty inaccurate determination. But I don't think the margin of error is that large so as to mistake 64% for 68% haste.
To repeat this test, you need:
1 melee DD preferably with a good deal of haste equipment and a weak, high delay weapon
1 DNC with 5/5 haste samba - they need to land samba before you make weapon contact, and they need to keep meleeing throughout the measurement - and for the control, obviously they wouldn't have haste samba active
1 BRD with march +2 instrument (document wind and singing skills)
1 RDM or WHM to cast haste
Some way of recording the time interval between the start of swing #1 and swing #1+n, where the larger the value of n, the more precisely you'll know the time between swings.
Interested in seeing some backup!
I tested Haste Samba a while ago. It's JA Haste. I haven't updated the thread in forever so info like this get lost easy :/ Sorry~

Are you going do testing on skill above 566? It's rather easily to obtain 566 skill at 80
Kinda wondering this myself, if they changed the tiers or added new ones.
