So Ithaca gets 63 average, and 45 miles to the southeast, BGM gets 83. The difference must the coastals and orographics. Ithaca gets the same LE roughly that BGM gets I bet, since the trajectory would be aligned the same for both cities.
I grew up in elmira which is due south of Ithaca, and that place averages 45 ish. No LE to speak of, and coastals nearly always are too far east.
