We've been using two or three hand stopwatches to time flying 200's for the last two seasons.  Human timing is generally considered accurate to the 10th of a second, but it's also prone to errors, people getting distracted etc.  So, John Lewis is developing a timing solution that will be automatic for flying 200's that won't break the bank of aboc.  Commercial systems start at around $3,500 or so (for two timing sensors and a stopwatch!) which is simply more than we can afford, but a home grown system is on the cards.

We'll keep everyone posted on it and it will be very well tested before we use it.
