After trying to deduce the skill tiers for Victory March and it's haste gains, it became obvious that the previous model of x/512 wasn't working. I started from scratch with a new model x/1024. The model is more accurate than the previous one, but there are relatively few changes. For example, Homam Hands being 3% haste = 30/1024... this is equivalent to 15/512 under the previous model.
-Recast can only be between 0 seconds and 255 seconds.
-Haste is calculated by the equation: y=floor( (1-x)*c )
Where:
y=New delay or new recast
x=Haste amount
c=Base delay or base recast
-Haste attainable from equipment is capped at 256/1024 (25%)
-Haste attainable from magical sources is capped at 448/1024 (43.75%)
-Weakness caps you at -1024/1024 magical haste. (100% Slow) *[This was changed in a patch and no longer applies.]*
-Fast Cast appears to be applied after or before the effects of Haste and only affects recast.
-Dual Wield is applied before the effects of Haste and only affects Attack Delay.
The following items have been verified:
Blitz Ring = 11/1024
Homam Hands, Feet, Dusk Feet+1, Dusk Hands = 30/1024
Homam Pants(not counting Fast Cast) = 30/1024(Most likely)
Ace's Helm = 40/1024
Turban = 50/1024
Speed Belt = 61/1024
Haste Spell = 150/1024
Rune Chopper = 90/1024
Advancing March (/w +2 horn) = 96/1024
Haste Belt = 102/1024(Magical haste)
Catastrophe = 102/1024(Equipment haste)
Fast Cast:
Loq Earring = 10/1024
Homam Pants(Fast Cast only) = 20/1024(Most Likely)
Below is a chart /w tested values of haste on Victory March[Editted: 1/10]:
http://trutlels.com/omenfiles/vicmarchchart.JPG
Advancing March /w +0 instrument: 64/1024
Advancing March /w +1 instrument: 80/1024
Advancing March /w +2 instrument: 96/1024
+1 Instrument grants +16/1024
+2 Instrument grants +32/1024
=========================================
I also went back and redid some delay tests~
My first test, was to use Relic Scythe(999 Delay):
SV Marches x2 + Haste Spell + Capped Eq + Hasso + Desp Blows = ~(956/1024)
(1-956/1024) * 999 = ~66.3398 delay
66.3398 delay / 60 = ~1.105 hits per second
1.105 x 30 = ~33.1699 frames per hit
My test showed 33.43 frames per hit. This is sufficient enough to assume we're reaching the expected ~93.35% haste.
I also performed delay tests on a crab, /w and /wo slow.
Robber Crab(Kuftal):
Normal: ~242 Delay (~121.1 frames per attack)
Elegy + Slow: ~411 Delay (~205.4 frames per attack)
Estimated Slow% from this data: ~70%
This test shows that slow follows the same equation for haste, and acts as a negative haste value.
To better show the accelerating gains of haste, I made a simple graph. The idea is to show that at normal haste values, adding haste is not as benficial as it is at higher values. X-Axis is Haste%, Y-Axis is the number of times you'd attack in a normal attack round compared to base delay.

===================================
All of this data can be deduced by first making the assumption that haste values can be accurately described by x/1024.
Using Victory March and varying degrees of skill gear, combined with dread spikes recast, you will find changes in recast at:
471/472 skill
505/506 skill
545/546 skill
Normalli a given recast will give you a range of 4-5 possible values of Haste values. Since the recast changes at those skill markers, we can accurately determine that they are the lowest and highest in their respective skill ranges.
Since you are able to change skill gear and increment Victory March by 1/1024 you can accurately combine it with equipment and look for where the recast changes. After finishing the March chart, I was able to test everything precisely.
I did test whether sing/wind had different potency, but it was not the case. Both are factored equalli. The max skill I was able to obtain on my friend's brd is 551. I'm missing a possible 9 skill total which is why I'm unable to test any higher march tiers.
Edits:
-Changed chart to accurately reflect March /w +0 instrument.
-Changed Homam Pants info, added small note on fast cast.
-Thank you Valyana of Ramuh for correcting mistakes~
-Tested up to 554 skill and updated chart.
-Added disclaimer and a note on weakness.
