Yes, exactly, that leaves you more time for drinking beer or wine or [insert favorite beverage here].Tap to tank would knock my waters changes down by half.
If you're worried about temperature, and if you have a faucet with a double tap then all you have to do is to grab thermometer and set the temperature coming out of the tap to the same as the tank, or within a degre or two. Then connect the hose. If the tap is an outdoor tap, with only cold water, well then this is a no-go, but intdoor faucets work fine. As Chandler mentions just add the dechlorinator to the tank while the water is running.
Cheers,
