Why do I need to enter my steps or sync my pedometer every day by a certain time?

A Step Ahead is a turn-based game, where each day of the challenge is a turn. Each night, the game engine runs and calculates all of the steps, tracking, combat, zombie conversions etc. for the previous day, concluding the day-long turn. There is a daily cutoff (specified for each individual group/company) after which steps/tracking will no longer count for the current day because the game engine has already finalized the previous day’s turn.
