Retrieving total haste percentage

[panker]

As the title suggests, I find myself in need of knowing the total haste modifier for a character (ranged haste in this case). The combat rating retrieval functions do exactly that and only show haste gained from ratings.

I figured you could get an accurate value by doing (base weaponspeed)/(modified weaponspeed), but then surprisingly I ran into another problem - which was retrieving the base weapon speed. Before I succumb into tooltip parsing, I'd like to know if there's another way of getting this? GetItemStats() doesn't seem to include it.
