When's My Turn?

Hospital wait times are notoriously long, and mostly spent staring intently at the queue display board.

While trying to mentally calculate when your turn will come based on how fast numbers are being called is a universal pastime, I was bored enough in the waiting room to build a small web tool to semi-automate the math.

You enter your ticket number, and each time a new number pops up on the clinic's display, it tracks the intervals to dynamically project an estimated call time using linear regression.

A small utility to take the edge off the opaque anxiety of waiting by turning an unpredictable queue into a visible countdown.
