For speed I used the formula:

delay = 725 * .85 ^ level + level

Where delay is the time (in milliseconds) before the block falls one row -- That equation reaches its minimum at level 30 (35.5 ms delay) and begins to climb again until delay = level (basicly the game slows down about 6ms per drop by level 41). However, I was modeling a certain behavior, and you might have better performance with a more general equation:

delay = delay_at_level_0 / (level + 1)

Where delay_at_level_0 is a constant
