At the same time some pull better at a standard ratio. The machine also plays a part in the dose. Not all machines will take a high dose. For some machines with smaller portafilters a 16 gram dose is updosed since many levers were designed to pull a 14 gram dose at a normal brew ratio. Ignore the dose size and focus on the brew ratio, capacity and personal taste of your machine. In the end, if you are insistent on dosing 20 grams, you may be better off to sell the machine and get one that will take a 20 gram dose even though you are still pulling the same brew ratio with your current machine using a lower dose. Kind of a pointless upgrade but if you just have to have 20-21 gram doses, knock yourself out.
