How to calculate attack speed of dual wielding skills?

"Dual Strike" and "Cleave" use weapons in both hands to hit.
How to calculate attack speed in this situation?
And do dps in character stats display properly for this two skills?

Do I post in wrong place? If this, sorry :)
I thought game mechanics questions should be here.

Damage: The DPS display is inaccurate for this skill because it can't account properly for dual wielding attacks.

I found this on wiki, which confused me.

When not using Dual Strike or Cleave, dual-wielding uses a SPA (seconds per attack) average; 2 aps is 0.5 spa, 1.5 aps is 0.667 spa, 0.583 average spa, 1.71 aps.

I'm pretty sure Dual Strike and Cleave use an APS average; combining 2 aps and 1.5 aps would give 1.75 aps.

In any case, Dual Strike and Cleave should be changed to use a SPA average.

Dual weilding normally doesn't really use an SPA 'average', it just does one attack, then the other attack, and so of course the total time take for both is the seconds per attack for each one added together.

I don't see any reason why cleave/dual-strike should use an SPA average, any more than an APS average.

IMO, it should just use the lowest attack speed of the two weapons. There's no reason why you should be able to swing a slow weapon faster just because you're also swinging a fast weapon at the same time.

I think it makes perfect sense from a game-logic point of view - there's no reason Ice Spear should have 0 physical damage, for example, as I'd imagine a spear of ice slamming into you would cause some amount of physical damage.

Averaging attack speed is a "fair" and intuitive way to balance dual-wielding in the same way that, say, axes being unable to cause bleeding effects is a way to balance weapon skills.

To Arxile: To view the true attacks per second for a skill, just press C and click it. I'm pretty sure this is accurate?

So most skills use SPA average, "Dual Strike" and "Cleave" use APS average.
But skill stats in character stats panel always use SPA average, so the dps is not accurate for "Dual Strike" and "Cleave", right?

I want to emphasize that I'm still not sure precisely how Dual Strike and Cleave attack speed work. However, yes, that's my understanding of how they work at the moment.
