Give it time as i wasen't realy monitoring it after i changed the setting. I droped the setting down to 50% after i posted and now some units have completed in 1 min 3 seconds. It might not work for everyone and it won't show up instantly after the change. All i can say atm is give it a try and see if it works for you. If not no harm done i guess as long as it don't slow things down for anyone.
