more practical but still fairly slow method, isn't there a way to know the chain length byjust looking at number of gears and chainring teeth? like http://blog.brilliantbikes.co.uk/2015/02/brompton-chain-sizing-guide.html
Get a box of toothpicks / matches and pop one into the chain every 10 links.
No need to count to 100.
