40/40

From Guild Wars Wiki

40/40 refers to a wand/offhand weapon set with both 20% HCT and 20% HSR mods on each weapon.

[edit] Chances

With a doubled 20% chance for activation of HCT or HSR, the total chance of getting the bonus at least once is 36%.

The chance for one of the bonuses to be activated twice is 4%. This means in case of HCT that the spell will activate four times as fast as normally. The HSR bonus will take effect only once in any case since skill recharge modification is limited to 50%.
