Remember 100 Meters or 300 Feet is CAT5 cable length limit.
From practical experience: The theoretical indeed is 329 feet, 100m. As it goes, 300 feet seems to be the max under typical conditions. I’ve seen anything as short as 290 feet start dropping packets due to length, but I’ve also seen disasters at 80 feet when run directly by an unshielded, fluorescent light.
