Red, now that you have the initial lock done, it will start up faster. TTFL will be shorter because the Garmin, like nearly all GPS units, downloads location assistance (not the actual name but more descriptive of what it does) on the first lock, it will use that for a period of time and discard it when it downloads a new file in the future. Its a function of the GPS system, not the Garmin itself. It then uses that info to know where to start looking for satellites. On you upcoming century ride it will likely be up and ready to go in less than one minute. One thing to keep in mind, the barometric calibration of the altimeter does take more time and is temperature dependent. So if you are going from a warm car to a chilly start of the ride, take the Garmin out first and let it sit outside on the bike while you get everything else ready. By the time the ride starts, your altimeter will be as correct as possible.
