Which swing speed calculation is correct?

[Varrius]

When you plug 180 stamina, 4.25 speed weapon and 45 ssi into the stratics calculater, it shows that the speed is the same as having 55 ssi. Bothing swinging at 1.75
When you use this other site, which a lot of people have used for years, there is a difference from 45 ssi and 55 ssi, it has 55 ssi swinging 1.5

I'm trying to figure out which one is correct.

Here are the two links...

Stratics is right, use these links:
UO Stratics - Combat
Swing Speed - UOGuide, the Ultima Online encyclopedia

Let's calculate it without using a calculator. From: Weapons: All | Mythic Entertainment | Ultima Online

Speed indicates base Swing Speed in seconds. To determine actual swing speed, use the following:
1. Take the speed in seconds, above and multiply it by 4 to get the speed in "ticks." If you are barehanded, you swing at 2.5 seconds, or 10 ticks. Example: The Halberd (4.25 second base speed) has a base speed of 17 ticks.
2. Figure out Stamina Ticks (Current Stamina / 30, rounded down.) Example: Current Stamina = 50. So Stamina Ticks = 1.
3. Figure out Swing Speed Increase item property modifier. Example: 20.
Apply those results to the following:
a. Hit Start = ((Base Weapon Speed - Stamina Ticks) * (100.0 / (100 + Swing Speed Increase)))
ex. Hit Start = ((17 - 1) * (100.0 / (100 + 20)))
c. Make sure minimum swing time is never less than 5 ticks (1.25 seconds).
ex. The calculated Halberd Hit Start speed = 13 ticks (3.25 seconds)

4.25 weapon speed = 17 base weapon speed ticks
180 stamina = 6 stamina ticks

Hit Start = ((Base Weapon Speed - Stamina Ticks) * (100.0 / (100 + Swing Speed Increase)))
= (17 - 6) * (100 / (100 + 55) ) = 11 * 100 / 155 =~ 7.096 ticks = 7 ticks (always round down)

7 ticks * 0.25 secs = 1.75

I programmed the formula into Excel a while back, and I am also getting a resulting SSI of 1.75 according to the info you provided.
