What's your favourite gear ratio?

I know close to nothing about gear ratio. Wwhat I do know is that I'm about to commute 12 miles one way to work, five days/week, with a track bike that have 170mm crank arms and a 50t/16t ratio.

Is this... okay?

They're all messing with you, swap out that 16 to a 14 otherwise you will never get to work in time.
