DPS Calculation Inaccurate

Im pretty sure there is something wrong with the way you calculate dps, for example, had 2 items on my warrior:
Item 1: 16-19 Damage, 34 dps, 0.9 speed
Item 2: 16-21 Damage, 32 dps, 0.9 speed
now im just wondering how an item with the same speed and base damage, and higher max damage would have lower dps?
A suggestion on how to calculate dps: (( base dmg + max dmg)/2)/ weapon speed
Just a suggestion, but i hope you can make dps calculation as accurate as possible.

EDIT: Nevermind this, it appears that i was looking at the wrong thing, I was reading the base weapon stats instead of the damage stats of your character, I am sorry if this caused any problems/confusion.

If one of these items affected one of your statistics (STR, DEX, INT) it will also affect your DPS.

If neither of the items had any sort of stat modifier on them (like +1 to STR) then it's definitely a problem with the calculation that we should examine.

Thanks,
