Loss of Lemmings: Zero
Jump one out, and Jump again over the gap. Pole Vault from the 6th yellow block. Shimmy across the gap. Make the Lemming a Runner. Hop from halfway along the last block before the gaps - it should get all the way to the right. When it gets down to the bottom right corner, make it a Climber. Throw a Spear from the second last block, so it lands in the block above the exit to create a step to break the horde's fall. Fill to release the horde.
