Obviously you don't want to use too much water and take in too much paracetamol but using really small amounts like some suggest will probably result in losing much of the codeine/DHC unless your CWE procedure is spot on..if using very small amounts of H2O then something as simple as forgetting to pre-wet the filter papers or not waiting long for everything to filter through can result in losing half of the end product since your liquid is now so concentrated....
Measuring how much liquid you start with and how much you finish with, along with working out how much codeine should be contained in each ml or water gives you an good pointer to your final yield....
Obviously losing 5% of your starting water is a much bigger deal with a very concentrated solution than it is with a very dilute one.
It might be getting too complicated but I always recommend working out the solubility of APAP at the temperature you're working with and using as much water as you can while ensuring (mathematically) that your end product contains the maximum amount of APAP that you're comfortable consuming (which is usually 1g).
