40/40

A 40/40 weapon set is one such that you have two modifiers for each 20% chance of Half Casting time, and 20% change of half skill recharge.

This does not provide a "40% chance of each". In fact, with halves casting time, you can get up to a 32% chance to halve casting time, and a 4% chance to quarter casting time. With Halves skill recharge, you can get up to a 36% chance to halve skill recharge. There used to be quarter skill recharge, but it was removed in the July 13, 2006 update.
