Item weight?

[TerrorBite]

for some reason i think that the decrease in WPF differs for weight from different armours, ie 1 weight from hand armour slows you down much more than 1 weight from body armour. Is this the case in crpg?

You are correct. 

For throwing/crossbow/archery WPF; head armor weight counts twice, body and leg armor counts once and hand armor counts six times.

Armor weight
Armor weight modified proficiency = base proficiency * (1 - 0.01 * effective armor weight)
Effective armor weight = 2*head armor weight + body armor weight + leg armor weight + 4*hand armor weight - 10
(Source: WaltF4, updated 31.7.2012 based on the new formula)

This means that every point of armor weight with helmet weight multiplied by 2 and glove weight multiplied by 4  over 10 reduces your wpf by 1%. Or the same put other way, any effective armor weight from the above equation reduces your wpf 1% per 1 point.
