Magnu420: short 1.5lt for the last of 6 X 4lt stripping runs or short 1.5lt for the 5th batch? Either way it's not the end of the world. You'll notice on the guide the original wash is stated as 26lt and this is to allow for the loss of up to 2lt during the clearing process leaving 24lt or 6 X 4lt batches. So the original size of your wash is critical if you want to follow the guide to the letter - but - again, it's not the end of the world.
If you only have 2.5lt for the last batch I would just add 1 litre of water and run it. You'll get less output - proportionate to the reduced volume - but you should get about 950ml-1lt of low wines to add to your spirit runs.
John51: I let the stripping run continue until the alcometer dips just below 20%. I reckon the power required to go any lower is just not worth it.
